[Key knife classification] What are the Outdoor keys for key knife classification?

Usually we classify the key knife according to the size, such as 58mm, 91mm, 111mm.However, according to the characteristics of the inherent work on the key knife, you will find a very interesting method:

What are the key knife classification

1. Modification type: Representative -model (scissors and cut nails, nails repair nails, toothpicks to remove teeth, mule eyebrows)

2. kitchen type: Representative -Standard (knife cut fruit, bottle liter, kick -up can be opened, plug the plug and wood plug, toothpick picks water cubes)

3. home: Representative -climbers/concise (knife cut fruit, scissors and cut things, rose up the bottle canal wood plug, hook litter bag, etc.)

4. Urban suburban: Representative -Hunter/Farm Lord (on the basis of climbing, there is an extra wood saw or replaced the cross cone. With the meaning of Outdoor, it becomes a common type in the city and the suburbs)

5. Tool type: Representative -guerrilla/craftsman/famous craftsman/work champion (knife, clamp, cutting, wooden saw, steel saw, frustration, chisel, cone, cone, is the combination of tools)

6. Comprehensive: Representative -mini champion/Swiss champion (modification, kitchen, outskirts, urban dwellings, tools are all complete)

7. Professional type: Representative -fishing/Traveler/computer Master/Firefighter/Rescue Tool

8. Defense type: Representative -sentinel (single opening, lock, long enough, you can "go straight" single -knife)

9. Wild appearance: Representative -hunter (cutting, wooden sawing wood, sickle stabbing grass, drilling cone drilling)

10. Mixed type: Representative -Poor/German officer (there are many types of this category. On the basis of the field of wildness, there is a cross -word cone to be repaired.

precautions

Through the above classification, you can clearly know which style of Outdoor multifunctional saber you want.

How to adjust carp in different seasons

spring

The warming of the carp is very strong. It will migrate the living environment with the change of water temperature. In the southern spring, in general, the activity of carp is still small. At the suitable temperature in March and April, part of the temperature, part of the part of the temperature, part of the part of the temperature, part of the part of the temperature.The two -pound carp will swim to the shallow water area near the shore to find food, and a small number of adult fish will find food in small -scale activities in the deep water area of the wide water surface, and weaken as the temperature rises or decreases in the morning and evening temperatures.It is also important. Because in the early seasons, most adult fish have not yet set seeds to throw essence. The "big belly" group of fish belly has always risen to affect appetite. Therefore, this period is not the ideal season for carp fishing.In the northern and even northeast regions, the foraging of carp activities in spring is almost zero.

summer

summer is the most active season of carp, and the change of meteorological conditions will also disrupt the activities of carp.The fisherman can interpret the law of carp in two periods: the first phase is the early stage of the rainwater. After a large amount of new water in the reservoir area, the water quality is improved, the amount of solubility is increased, and the fish is active.Especially adult carp will take this opportunity to start breeding offspring.In the cool drizzle or in the sunny morning, people often see large carps chased by large carps on the shallow beach in the shallow beach in large water areas.From late May to mid -June (the rain is slightly advanced or delayed sooner or later).Once the seeds are ends, the adult carp enters the food period, and it is almost all over the weather for food, and there will be a group of young carp to go to the shallow water area for food and play.Finding food with a wide water area is just fishing with sea rods.The second phase is the high temperature stage. The temperature is high during the day. After the sun rises, the carp swims to the deep water area. Foraging in the cool downstream of deep water.To grasp this feature and use the method of fishing, it is the best strategy to deal with the big carp.

autumn

The climate in autumn is cool. Some carp will travel from the deep water to the shallow water in the shallow water. At this time, there will be carp bite hooks in the long -term fishing, near, and shallow fishing, and it is very positive for foraging in the morning and evening.

winter

In the winter in the south, as long as it is a sunny day before mid -December, there will be higher temperatures. For carp that eats more than 10c of water, in the first half of the winter, it is still the "good date of finding food in the first half of the winter."Beautiful scenery", at this time, the carp will find food in the water areas of 2 meters from 78:00 to 4 or 5 meters from the water areas from 78:00 in the morning. Therefore, fishermen in various places often have the good news of winter fishing.

The state of foraging in carp activities will change with the quality of the weather.In the second half of the winter, the temperature was getting lower and lower. Occasionally, the temperature of the weather picked up, but it was not enough to promote carp activities to find food, especially in the north, so this period was basically fishing.

fishing carp bait formula

Sweet potato

Sweet potato (also known as Sweet potato) has a large sugar content and large viscosity, especially the sweet and more sticky Sweet potato.First wash the sweet potatoes, steam and cool the high -pressure cooker, cut into thin slices with a knife, and then use a pen hat (cylindrical shape) to press the small round bait on the Sweet potato chips.The king "and" Jinfeng ") are mixed, so that the small Sweet potato grains are sticking to the powder -shaped finished bait.When using, hang Sweet potato grains on the hook, and the powder bait on the Sweet potato grains scattered in the water. These powder bait scattered in the water seduce fish.You can also mix sweet potatoes into Sweet potato puree and mix it in finished bait or cake powder and bran powder as bait.

Cake powder mixed bait

Crush the cauliflower cake (or Peanut cakes, bean cakes), mix it with water into wet material, steam it in the pot, and mix various finished carp bait (such as the "old ghost" carp bait) when it is cool, add(Bone powder or fish powder, the bait is fragrant and fishy, the effect of fishing carp is very obvious.

Sesame sauce bait

Use bean cakes (Peanut cakes, sesame cakes are also fine) (about 500 grams), then fry the aroma, and bran (50 grams) also fried fragrance.Flour (50 grams), 250 grams of humidifying sesame scum, add some water in the fishing ground after the fishing ground, mix the above raw materials for bait, and can also be used as bait fishing for bomb hooks.

Sihe ~ Polying bait

Use 30 % cake powder (the best sesame cake powder, if there is no sesame cake powder, other cake Flour can also be done), three % of the Wheat bran is frying the aroma with the fire, and the water powder is used before use, and a small amount of fish powder and a small amount of animal blood powder are used.(Two kinds of Flour are combined to be 30 %), stir well, and add some Flour before the bait to increase the viscosity.

Fishy bait

500 grams of rice Flour, 100 grams of Flour, 50 grams of cake powder, 50 grams of fish Flour, mix the above bait with warm water, pinch into steamed buns, steam it for 5 minutes, open it after cooling, mix a small amount of fish powder and sugar), Put it in the bag and cover it slightly.

rice bean honey bait

Raw material:200Gcorn surfaceAs well as40g soybean Flour, appropriate amount of honey.

Production steps: Put all the raw materials in the bait basin, then stir it well, then add an appropriate amount of honey to it, then stir it evenly, then scald it with boiling water, then stir with chopsticks for stirringThen put it in the pot for steaming. After steaming, take it out of the pot and knead it a few times before you can use it.

Note: This is a simple and practicalCatfish baitAfter the production, it will emit a strong fragrance. It is paired with the sweetness of honey. Not only does the large body of catfish like it, but the temptation of carp will also be great.

rice bean mixed bait

Raw materials: 100g corn Flour, 20g soybean powder, 25g of Peanut sugar, 15g of Flour, 5g of lilac powder, appropriate amount of honey, 1 bottle of beer.

Production steps: First pour the raw materials into a clean bait basin, then stir it well, wait until the mixing is evenly put into the barrel, then cover the lid, then place it naturally for about 3 days of fermentation, and then ferment, and then ferment for about 3 days, and then ferment for about 3 days, and then ferment for about 3 days. ThenOpen the lid, you can smell the fragrance of the grain and a faint sour smell.In this way, this homemade carp bait is made.

[Method for polarizing mirror] How is the main purpose of polarizing mirror in polarizing mirror?

How to use Polarized mirror

There are two types of polarizing mirrors: round polarizer (Referred to CPL ) Line polarial mirror (simply referred to PL or LPL To.

They are in most consumer digital cameras (DC ) There will be no difference in upper. TTL Light metering function) SLR/DSLR Also DC And hope to share a polarizing mirror, it is best to choose a round mirror.In addition, the differences between line polarizers and round polarized mirrors, as well as why in modern times SLR/DSLR The reason to use a round Polarized mirror, in the clumsy book L.6 Zhang has a very careful explanation; but because it is not important for novices, it is omitted here. Interested friends, please refer to the clumsy book (there is a chapter in the link above PDF files).

There is a loop that can rotate freely on the Polarized mirror. Its function is to regulate the effect of polarizing mirror.The polarizer is usually two types: thick (general) type and thin type. The former may be thicker than the latter1mm Or more, when mentioning polarizers below, if there is no special explanation, it refers to thick (or general) polarizer.The thin Polarized mirror is for wide -angle or ultra -wide -angle lens, because too thick polarizing mirrors can easily produce dark corners.Generally speaking, if the camera lens ( 135 Movies) The equivalent focal length is at 35mm Above (including 35mm ), Thick polarizer should not have a dark corner; but if the focal length is less than 35mm The thick Polarized mirror is likely to produce dark angles, but this is usually related to the optical and mechanical structure of the camera mirror. It may not be the case for every lens, so it is best to try it before buying a polarizer.

The main purpose of polarizing mirror:

Reduce the reflection of glass, water surface, and non -metal surface, make the sky blue, and improve the saturation of the color of the picture.Because the Polarized mirror is dark gray, it will block part of the part that can reach the sensor chip Light, it will generally decrease1 arrive 1.5 Between Levels.In addition to the full manual exposure mode, the camera's optical metering system of the camera will be adjusted by itself in other (such as aperture prerequisites, or the shutter prerequisite) mode, but you still have to check whether the aperture or shutter speed selected by the camera will be used.

Reduce reflection

The reflection on the surface of the subject will wash away the details of the picture, or change the color of the picture. One of the most important functions of the polarizing mirror is to reduce or even eliminate the light that is reflected by the camera and enter the lens, but when the subject is metal, Polarizer The function is not very significant.The best angle of lowering or eliminating the reflection with a polarizer is that when the light source's irradiation angle and the camera shooting angle are made with the camera30 On the occasion, one (or two) deviates from 30 The time -effective use will be reduced, and the more effective the angle deviation is, the lower it will be.It is very simple to reduce the reflection with polarizers.After the composition is completed, rotate the ring in front of the Polarized mirror, and watch the scene window (or LCD/EVF ) The effect of polarizing mirror will be displayed. Once the desired effect is obtained, stop rotating and shooting.It should be noted that polarizing mirrors are not universal, and it is likely to be unable to completely eliminate reflection.

The most well -known application of polarizing mirrors is to deepen the blue of the sky, making the blue sky and white clouds stronger; however, if the sky is not blue (such as a cloudy day), no matter how good the polarizer is, the blue sky cannot be shot.But we should It is time to understand that only one of the sky will become bluer, and the other may not change. More importantly, the shooting angle must be selected correctly.There is a very simple rule for choosing shooting angle, first extending the index finger To the sun, then erected the big fingers vertically with the index finger, and turning around the index finger, so the direction that the Mark finger passes is to get the most effective shooting direction; in other words, the best shooting direction and the direction from the camera to the sun to the sun Droop straight!Please pay attention, the Mi fingers passed by360 Degree, except for the middle of the right, this time, this 360 Some parts in the sky, part of the ground to the ground, to the sky is the direction that can turn the blue and become blue.When the camera deviates from this direction (such as the shift in the sun or the anti -sun direction), the lower the effect. If it is more than a certain angle, the effect will not be significantly or even disappear.After looking for the direction of shooting, slowly turn the ring in front of the polarizer, and take the shutter after getting the expected effect.

In addition, because polarizing mirrors will reduce or even eliminate the reflection of the subject, the color of the picture shot with polarizer is also more pure than it is not in time, and the contrast is also higher. This is the theme of the next section.

increase the saturation of contrast and color

The reflection of the subject will cover up the original color and details. If the reflex characteristics of the subject in the screen are similar (such as the leaves), a faint reflection not only erase the original color, but also reduce the contrast of the picture. In this Affection In the case, the use of polarizers has the effect of reducing reflection, reproducing the color of the subject, and improving the comparison of the picture.The lower left photo is added with a polarizer but the lowest effect is used, and the lower right is the maximum effect; these two are extremely strong In contrast, the reflection of the leaves under the scorching sun distused the color of the woods, but to maximize the effect of polarizing mirror, and the color of the wood and the grass appeared, making the two photos very different.

If the camera cannot be equipped with polarizing mirror?

Many small and stylish digital cameras can neither install filters nor adding sleeves, but we can hold a polarizer in front of the camera to shoot, but how to adjust the effect of polarizing mirror?The method is very simple. First of all The direction of the mirror on the shooting of the lens (so the closer to the camera, the better), see the lower left photo; then turn the ring on the Polarized mirror, stop after the expected effect (below); finally move the adjusted polarizer to the lens to the lens Ahead (below Right), but the polarization mirror cannot be rotated, because once the direction of the polarization mirror is changed, the desired result is not available.

Practice this procedure several times, and try to take some photos to compare the results of use without polarizing mirrors. After several times, they will be handy.Most lightweight digital cameras have a small diameter, small,37mm The Polarized mirror is usually large enough (if it is suspected 37mm Too small, just use it 43mm ; 37mm Too big, try to try it 28mm ), Bring a polarizer with you, you can easily take photos with saturated color, blue sky and white clouds, and high contrast during travel.

precautions for using polarizers

First, polarizing mirror may be the most important filter in digital photography. It can reduce or even eliminate the light reflected by the subject, turn the sky blue, improve the saturation of the comparison of the picture and color.

Second, most consumer digital cameras can use line polarizers, but the vast majority (especially those with autofocus and metering function)SLR/DSLR You can usually only use a round Polarized mirror.If a Polarized mirror is used at the wide angle end, a thin Polarized mirror should be used.

Third, the use of polarizers will lose1 arrive 1.5 Grade light will affect the aperture or shutter speed of the selected; in other words, it is likely to use a large aperture (so the depth of the depth of the scene) or the slower shutter speed (then the movement of the movement It may be blurred and easily shake the camera), so you should pay attention to the aperture and the shutter speed.

Fourth, although the polarizing mirror has the effect of reducing reflection and turning the sky blue, but this effect is related to the angle of shooting. If the shooting angle is wrong, it is likely that the expected effect will not be obtained.Furthermore, when shooting with a wide -angle or ultra -wide -angle lens, because the viewing angle may be greater than the best angle of the polarizer, the sky in the screen may appear from very deep to quite light, that is, the blue color with uneven concentration.

Fifth, it is best to remove it from the lens when there is no need to use a Polarized mirror.1 arrive 1.5 In the secondary light, the second is because the effect of the polarization mirror is set to and the effect is more or less, so the polarizer may sometimes cause the anti -effect (such as filtering the expected reflection).

This article introduces the basic concepts, usage, and effects of polarizing mirrors, and lists some precautions when using polarizers.The effect of polarizing mirrors is difficult to simulate post -made software, even if the sky turns blue.if The boundary between the sky and the ground is relatively simple. When the post -made system is selected, it is easier to change the color depth. Once the boundary becomes very complicated, the part of the sky is a time -consuming and laborious job. Objects, it is better to use Polarized mirror to adjust the effect when shooting.Furthermore, if the picture loses the details due to reflection, no matter how good the post -made skills are, there is no way to make the details and color that has not been recorded. Come.For these reasons, polarizing mirrors are a filter that cannot be completely replaced by post -made software.

1. What are the common faults of mountaineering sticks

1. Stuck and lock: The most common reason is because the operation is wrong, such as the lock is too tight or too loose during use.

2. cycling rods: It is usually caused by errors for the force point, which is usually the one that changes the badly.

3. Polar tip wear: After using it for too long, it becomes Smooth and the anti -slip effect will become worse. At this time, it is recommended to change the tip of the stick.

4. Metal oxidation: When you go home, you do nt wipe or dry immediately, it will easily lead to oxidation. At this time, the Climbing stick will be stuck.

2. How to repair the Climbing stick

1. What should I do if the Climbing stick is rust and oxidize

When maintaining a Mountaineering stick, you can use a very small amount of rust removal to treat the rust on the surface, but before use, you must remove all the oil on the surface so that it will not affect the adjustment of the Mountaineering stick.In addition, you can also use very fine scrub paper to remove rust on the surface, and keep the lock function of the climbing rod is not affected.[Although this may wear out the indication scale above the Climbing stick] Using the rotating lock -locked Mountaineering stick may fall due to the rust rust of powder, blocking the locking rings to affect the locking effect, so when maintenanceIt is necessary to remove the rust of the rings, especially before using them to use them, be sure that the inside is very clean and does not contain any rust and oil.

2. The Climbing stick is not tight and stuck

There are two common locking methods for climbing rods:

outer buckle: The fast -bucking rod is not tight because the snail is loose. When it is loose, the spacing of its clip will become larger and it will not be able to hold its next section.

[Solution] Take a Swiss knife or screw up, and lock it a little bit when you hold it, and the snail teeth will become tight.

There are two kinds of materials for common climbing sticks: plastic fast buckle, aluminum alloy fast buckle.The plastic fast buckle is slightly locked with the screws, and then test whether the looseness is appropriate.The fast buckle of aluminum alloy is sometimes difficult to lock. At this time, you can lubricate oil on the turning point.

Internal lock type: The suspended Mountaineering stick is not tight or stuck, it may be that the expansion clip in the middle is stuck, or the expansion clip runs too much.The length is often adjusted, and the Mountaineering stick is transferred too many times).

[Solution] First remove the expansion, and then reinstall it. The most important thing is that the teeth must be aligned, and then put it back.The expansion clip runs too much or is not aligned, at this time, you can pull it down and install it again.The expansion clip is not aligned, just pull it out and adjust it, then put it back.

3. How to avoid the Climbing stick on the way to climbing

It is recommended to check the locking part before departure and whether the Climbing stick structure is normal.However, if you are unfortunately broken on the way, it is recommended to keep the climbing rod completely preserved for manufacturers to repair and replace complete parts.Generally, we still recommend buying a good Mountaineering stick to avoid the climbing rods during the climbing on the way to the mountain.

Do you bring a rope when you go out and Outdoor?If you do nt carry it, it is recommended that you put a few special ropes of different diameters and different lengths in your bag when you finish the loading. The rope weight is light and easy to carry.1000 grams, the weight of the ten -meter 5mm static rope is about 200 grams. Bringing the rope will bring great convenience to your outdoor activities, and it will also bring a certain security guarantee to your outdoor activities.Don't simply think that carrying ropes is just a matter of leader, and the Outdoor environment is different. I hope that everyone will constantly explore more ropes in outdoor activities and play more functions of ropes.It is good to use the rope to expand some self -rescue.What needs to be reminded is that everyone should choose to buy a special rope (UIAA-Gundenglian Certification Product). Usually, you should often check the integrity (wear) status of the rope.And the practical method of knot ropes and ropes.Let's talk about some of your previous wild experiences about the various uses of ropes (non -mountaineering, Rock climbing version) when surviving Outdoor survival.

1. Dangerous road sections can be trapped and the auxiliary personnel can be passed by ropes. When multiple people pass at the same time, do not fix the rope on the body and Backpack.Way).

2. You can be used as a cold (sun) rope when you are resting. You can also tie up the canopy with the environmental needs, hand warfare and other things.

3. It can be used to make a simple stretcher for bundling, and can also support the use of aluminum alloy bars, tree sticks and other parts with the need to use aluminum alloy bars, tree sticks, etc. (using shoelaces to be bundled with the use of aluminum alloy bars, tree sticks, etc.The next policy).

4. Detecting the depth and rough width of the ditch, the depth and general width of the ditch (adopt a binding stone to the opposite side, judge the width according to the water falling point of the stone), and can use the rope to transport the personnel and equipment such asUnder the security and stable front question, rope can also be adopted with high and low -fixed slip methods).

5. lighting and anti -animal torch handles, under special circumstances, close the ropes on one end of the dry branches, and then pour the carried fuel oil or consumption oil to ignite. This method is characterized by the burning time and more durable.

6. It can be used as a night camp alarm and pull rope. After Hiking and Camping, due to the deep degree of sleep and sleep, you can tie the two ends of the rope to the GG and MM tents. Once an accident occurs, you can pull each other to wake up. You can also follow the camp according to the camp.The environment pulls the rope as a warning rope in the camp (the rope can be tied to the items that can make a crispy sound that can make a crispy sound).

7. In the narrow and slippery and steep slopes where the Backpack is not convenient to carry the Backpack at the same time, the rope can be used to use the method of separating people and Bags to pass.

8. After the personnel slip (fall), you can use the rope to implement rescue (according to the actual situation, you can use multiple ropes in parallel or series) to climb the better helping personnel.The length is generally controlled within the length of the human body. If the rescuer is a woman, the rope can be appropriately shortened. If necessary, you can also use multiple ropes to edit the soft ladder.

9. In the dangerous location (such as steep slopes, cliffs, etc.), the road personnel are used for safety protection on the line staff.

10. In the high temperature season to prevent food deterioration, the food can be closed (sink) into the water body and tied them on the food Bags and shore trees or other objects to prevent the water from being flushed away.

11. Used to strengthen the Tent under special weather conditions, it can enhance the wind resistance and snow resistance of the Tent.
