Is it easy to use?

The commonly said to be a scientific, practical, efficient, and convenient knife Tool that is recently studied, which is suitable for various kitchen knives, Outdoor tools, scissors and Damascus knives and ceramic knives.It is characterized by the traditional single -sided grinding knife into a double -sided grinding knife, which makes the method of grinding knife, angle, efficiency, etc. have undergone fundamental changes. The most blunt knife does not require more than half a minute.The efficiency is really unparalleled. The grinding Tool of the knife is made of refined with special materials. The service life is particularly long, and the cheap and cheap operation is simple. It is an indispensable good helper for housewives kitchen.

Principles of knife

Answer: The thickness of the tough mouth of the kitchen knife is generally 0.02mm, and if we thicken, we think that it is "unhappy", and then it will appear rolling or easy to fold. This thickness is the best.Solding on the knife device is to use the dense tough spots of the mill to cut off the tough mouth to make it thinner.

How to use the knife Tool?

Step 1: Fandify the grinding knife stick down and gently click on the flat desktop.The angle of the knife body is about 20 degrees with the corner of the knife and the knife stick.

Step 2: Then gently twitch the knife in the direction of his body.

Step 3: Change to the other side of the grinding stick, and grind the other side of the blade in the same method.

Step 4: Repeat the movements in the second and third steps, grind five to ten times, and the blade on both sides is squeezed alternately.

When grinding the knife, in the process of drawing the handle from the tip of the knife, you must always ensure that the angle is 20 degrees.The speed of speed when twitching does not affect the effect of grinding knife.If you are used to your right hand, please hold your left hand and hold your knife in your right hand.If you are used to your left hand, the opposite is the opposite.

Note: Always keep the grinding stick in the same direction when using.

Grinding stone

Prepare a knife stone, and the grinding stone is fine particles on one side, and on one side is thick particles.If the blade curls, the gap can be polished and flat with the thick particles. If the condition of the knife is still, the fine particles are used.

How to grind the knife?

The blade of the cutting knife is relatively sharp, and the angle of the blade of the left and right sides is different. From the left, the blade is almost vertical on the knife surface. The angle is small, so the angle of the left side of the knife is small.

Start the grinding knife, the grinding knife stones should be kept moist. When the knife is grinded, it is better to rinse with long flowing water. The grinding knife stones must be fixed.

When the left blade was grinded, the angle was small, and the fingers of both hands were tightly clamped with the knife body, and the angle could not change.Move back and forth with the grinding knife stones, pay attention to rubbing hard in the body, and do not force when pushing forward.

When the right blade is grinding, the angle is slightly larger than the left blade, and the angle remains unchanged. It moves back and forth with the grinding knife stone. Pay attention to the force when pulling towards the body.

After grinding it once, observe whether each paragraph of the blade is sharp, and you can use your thumb to lightly scrape the touch along the vertical direction of the blade. If you feel slippery, it is not sharp enough, but you can wear it in this section of the blade.

How to grind the Bone knife?

The knife knife is thicker, and the blade on the left and right sides is the same angle, and the angle is large.Therefore, when the Bone knife is cut, the angle of the blade and the grinding knife is large, so that the Bone knife is durable.

1. Several types of fish wires are divided into

The fish line is one of the important components of fishing tackles. Whether the fishing line is properly related to the fishing effect directly. For example, the choice of the type of fish wire is to pay attention. There are many types of fish lines. According to different classification methods, different types can be divided into different types:

1. According to the material

(1) nylon line:nylon wire is also called traditional lines or four -color lines. Generally, resin materials are made of resin materials. It is made of machining filaments. This fish wire has no color transparent, strong tensile, good elasticity, fast water cutting, and high fishing sensitivity.Durable, durable, soft, not easy to be crispy in winter, and verticality, so the nylon line occupies a dominant position in the market.

(2) Carbon cable:Carbon lines mainly refer to a fish wire made of carbon materials during the manufacturing process. This carbon -based fish wire is more abrasion -resistant, but the ductility is poor.The proportion of the carbon line is greater than the proportion of water, so its water cutting is better, which is more suitable for use in the rock fishing.Because the texture of the carbon line is relatively hard, it is often used for the eldest son line or tie of the Ship fishing.

(3) Weaving:It is a fish wire woven from multiple silk threads. The early weaving lines did not add a membrane, it was easy to absorb water, and it was not easy to maintain. However, because of its abrasion resistance and tensionHousekeeping, but the water cutting is poor.There is also a waterproof woven wire that adds a membrane technology during the manufacturing process, which is made of multi -stranded weaving lines, also known as fire lines.This weaving wiring is also good, but its damaged part is easy to form a hair ball, which is easy to break and the texture is harder.The fusion line is a weaving line that adds a multi -bhomistarian nylon line to the weaving line, and in this process.Its advantages are high tensile values and abrasion resistance.Because the nylon wire is added to the production, this thread is softer than the normal wiring and good back.

(4) Ceramic line:The ceramic line is made of high -molecular aggregate materials. In the formation of the online body, it is made of special resin to fill the spare special resin to improve the tensile strength and waterproofness of the fish wire.Then add the second layer of special resin to enhance the wear resistance of the fishing line.Finally, add special resin to the third layer to improve water resistance.The fish wire of the ceramic line has excellent tensile strength and abrasion resistance. It is not easy to nodule, light quality, and the feedback of fish feelings is more sensitive.

(5) Ultra -strong PE fiber fishing line:Taking the super PE fiber as the raw material, the surface of the thread is added with a lubricant to improve the layer on the surface of the fish wire.This material of the fish line is durable, long -lasting, and can prevent wear and fading, reduce tangels, and knots are more convenient. It has the characteristics of resistance, no cutting wires, durable performance, and fine line diameter. It is suitable for fishing as fishing.Line, kite line, water sliding traction line.

(6) Synthetic fish line:The synthetic fish wire is the process of adding other materials to the finished product during the production of the nylon line, so that the line can float on the fishing line that floats on the water or suspended in the water.Suitable for the semi -floating water line as the rock fishing, the full floating line containing the parade material, and the resin processing lines to add tensile substances.

2. Press the source of the fish line

It can be divided into three types: domestic, imported and joint ventures.The raw materials produced by joint ventures come from imports and are processed and produced by domestic. Many people like to use the lines produced by China -foreign joint ventures, because their prices are cheaper than imported, and the pulling force and technology are also applicable.

3.

It can be divided into powerful lines, super -powerful lines, and strong strength lines.

4. Press the color score

There are many types of white, light blue, dark blue, yellow, light red, color lines and other types.

5. Divide in fishing

It can be divided into competitive lines and leisure lines. The competitive line is a fish line designed for competitive. The leisure line is a non -professional line designed for the low requirements of the line.fishing people.

Second, which type of fishing line is easier to use

There are many types of Fishing lines. Different types of fish lines are suitable for different fish feelings. Generally, it is not easy to say which fish line is best. When choosing, it is mainly based on the fishing environment and the types of fishing.EssenceA good fish line generally requires the following four requirements:

1. Good liquidity

The so -called liquidity is that the thread remains less in water after water.

2. Strong tension

That is, strong, durable, and not easy to break.The Fishing lines sold by Fishing gear stores will indicate the tension of the fish line on the outer packaging, which can be purchased according to the needs.

3. Do not bend and deform

No matter how entangled the fish line, it is vertical after letting go.The curved thread is easy to make the hook in the water tilt, the fish is not easy to hook, and it is easy to decide.

4. soft

Whether it is a thick line or a thin line, it should be soft, and it should not be hard after a period of time, indicating that it is a good line.

Outdoor candle windproof method

1. Material: candle newspaper glue

Method: Use glue to paint the candle on the side of the newspaper. Remember to wrap it strictly. Don't leave the gap.

To light the candle, the newspaper can exceed the candle core, so that the wax oil is merged into the newspaper to increase the combustion brightness.

principle: Candle is burned by dipping the candle oil through the candle core. After the newspaper is soaked in the candle oil, it can enhance the combustion brightness and maintain stability of the candle.

In the case of about four -level Outdoor wind, the candles will not be blown out.If you wrap a multi -layer newspaper, the effect seems better.It can be used as a small torch outdoors.Note that the newspapers cannot be wrapped too much. Three or four floors are enough. Too much should be "cutting the west window candle", otherwise the fire is small.In addition, I tried paper towels, and the whole candle was burned.

2. Material: mineral water bottle

Method: Cut off the bottom of a mineral water bottle, remove the outer packaging paper and remove the bottle cap, you have a windproof light used in the wild. Its "power" is large enough and the work efficiency is improved a lot.

3. The material is easy to pull

Method: Taking the high midpoint of the tank, draw a 10cm line as a marker line, and draw a mark at the middle point, use scissors or knife on each parallel parallel area of the upper and lower parallel places to cut the mouth of the mark line.Cut along and down along the marking line, until the scissors marked line is cut up and down the parallel lines, open, and a candle windproof cover with a "door" is ready.

Lighten the candle and put the candle into the windproof cover.

Candle ingenious windproof match

In the wild, the fire species is almost everything.It is important to bring windproof match, but if you can't buy such a match, you can also DIY.The method is very simple. First, the candle is melted and evenly applied to the ordinary match. When used, remove the wax on the match head.

Pay attention to Outdoor candles

It is best not to order candles in the Tent at night, try to use Tent Lights or flashlights, headlights, etc., because if you order candles, if the Tent is not ventilated at night, it is easy to be carbon monoxide poisoning!

[UV -proof glasses] How to identify the UV -proof function of Sunglasses, what is the coating

What is UV -proof glasses?

The light emitted in the sun is: visual light, infrared, ultraviolet rays, etc.The ultraviolet rays are seriously harmful to the Skin, eyes, etc. of the human body; the ultraviolet rays in the light released by the sunlight are divided into UVA, UVB, and UVC.It is the light of burning black Skin. Most corners of the eyes will absorb this UVB light, so it is necessary to block this light source.

Because UV glasses have the function of polarizing light, they can block all harmful light without affecting the visual light through, which can truly achieve the function of protecting the eyes.

How to identify the ultraviolet function of Sunglasses

Selecting Sunglasses depends on its lens quality, and pay special attention to the function of Sunglasses.So, how to identify whether Sunglasses have the function of anti -ultraviolet rays?In fact, it is not difficult. Put the Sunglasses on a 100 yuan RMB and use a purple light to identify it.

Experts said that the main role of Sunglasses is to prevent strong light and string light, especially ultraviolet irradiation, which protects eye health in summer and is not damaged.

Therefore, when purchasing, you must pay attention to whether there are "UV400" and "UV" logos on the lens and packaging. At the same time, the UV -proof test is also required.

Method 1. Look at the label of Sunglasses

There are Sunglasses with anti -ultraviolet function, generally there are several clear ways:

a) Mark the "UV400": This means that the lens's cut -off wavelength of ultraviolet is 400nm, that is, the maximum value of the maximum value of the spectrum transmission ratio of less than 400nm in the wavelength ()

b) Mark the "UV" and "UV prevention": This means that the lens's deadline for ultraviolet is 380nm, that is, the maximum value of the maximum value of the spectrum transmission ratio of less than 380nm below 380nm;

c) Mark "100%UV absorption": This means that the lens has 100%absorption function on ultraviolet rays, that is, its average transmission ratio in the ultraviolet interval is not more than 0.5%.

The Sunglasses that meet the above requirements are Sunglasses that truly have protection for ultraviolet rays.

Method 2. Use banknotes to verify

In the absence of instruments, ordinary people can also detect whether Sunglasses have the function of anti -ultraviolet rays.

Take a banknote, put the Sunglasses on the anti -counterfeit watermark, and use the banknote pen or the banknote inspection machine to take a look at the lens.If you can still see the watermark, it means that this pair of sun mirrors are not anti -ultraviolet. If you can't see it, it means that this pair of sun mirrors is anti -ultraviolet.

What is the coating of UV -proof glasses

The most effective and most commonly used method to avoid radiation light caused by damage to the eyes is to wear protective glasses.The so -called protective glasses are a filter that can change through light and spectrum.

This type of glasses is divided into two categories. One is absorption and one is a reflex. The former uses the most.

When the lens is manufactured, a part of the metal oxides are added to the general optical glass formula, such as iron, drilling, chromium, cricket, nickel, manganese, and some rare earth metal oxides such as harmony.

These metal oxides can make the glass selectively absorb the electromagnetic waves in a certain band of light, such as the oxide of the and iron can absorb ultraviolet rays in large quantities.Using this glass lens can reduce the amount of some wavelengths through the lens, reduce or prevent damage to the eye.

1. Absorption filter

Also known as Sunglasses.The transmission rate of visible light is about 20%, and the absorption of ultraviolet and infrared is better.There are many colors such as light green, light gray, and light tea, which are used to make sunshade and snow work protection glasses.

Among them, light gray lenses have minimized color recognition; light tea glasses make the blue sky look darker, which reduces the green light through it; the light green lens reduces red light through.

Second, reflective filter

The absorption filter is absorbed by the lens to some wavelength light to reduce the strong light in the eye, but because the lens absorbs certain light, it becomes heat and release, especially the infrared lines and other waves are longer.The light of light makes the eyes feel uncomfortable due to the accumulation of heat.

In actual work life, many situations are combined with absorption and reflective type, that is, a layer of high reflection membrane is placed on the color lens to make the filtering effect more, such as welding, chlorine -library welding, plasma cutting and other operators.You can use this method to solve it.

What kind of sleeping bag can be divided into

1. Classification according to the material

1. Plel sleeping bag

The down sleeping bag is divided into duck down and goose down. The temperature of the goose down is slightly higher than the duck down.The down sleeping bag is relatively warm, easy to squeeze, easy to maintain the original, and the use period is long. The unfavorable factors are the high price and water absorption.

2. Cotton sleeping bag

The filling of cotton Sleeping bags is chemical cotton, which has many types. Generally, seven -hole cotton, nine -pore cotton, and P cotton are better.The cotton sleeping bag is better anti -hygroticism, and the wet cotton sleeping bag can still maintain warmth. It has the advantages of easy dryness, low price and other advantages, but its quality is compared

The down sleeping bag of the same level should be heavy, it is not easy to squeeze and loaded, it takes up the Backpack space, and the service life is shorter.

3. Plush sleeping bag

The fleece sleeping bag is sewn with Fleece, which can be used as a summer sleeping bag or a sanitary sleeping bag.It can also be used with other Sleeping bags at low temperature to enhance the warmth effect.According to time experience, a -3 -degree sleeping bag can increase the warmth effect after the fleece sleeping bag can be increased by about 5 C.Its thermostat is usually between (10 C and 25 C).

4, cotton sleeping bag

The cotton cotton sleeping bag is that the filling has two kinds of ingredients: down and cotton.It integrates the characteristics of down and cotton Sleeping bags.The back is cotton. Sleeping on it does not directly pressed to the end like a down, and the face is down to keep a better warmth than cotton.The price is also between down and cotton.However, there are not many products in this regard.

2. Classification according to styles

1. Mumini -shaped

The feet of this sleeping bag are relatively narrow, and then go up to the shoulder wider. Finally, there is a head pocket with a temperature beam above the shoulder.A suitable headp for tightening should be tightened to prevent the cold wind from blowing in.Considering that people are the most cold when they sleep, some mummy -shaped Sleeping bags are particularly thickened in the lower part, and some styles are designed with thickened foot pads.

2. Semi -long Square

While saving volume and weight, this sleeping bag takes into account the requirements of sleep comfort.Most of these Sleeping bags have head pockets.In order to obtain the effect of teaching well, its shape is generally relatively compact.

3. Envelope

Most of these Sleeping bags are used for wild Camping under warm conditions. This is because the original intention of this sleeping bag design is to maximize the requirements of people's requirements for the comfort of the wild Camping. As a result, it inevitably leads to more heat loss.This kind of sleeping bag can generally pull the zipper as a cushion, and there are generally no special head pockets.

Detail design introduction of Outdoor Sleeping bags

1. chest wall edge wall

Early Sleeping bags are rarely set on the side walls and chest walls. In use, people find that the upper mouth and the zipper will leak wind, which is not conducive to keeping warm.As a result, the chest wall and the side wall are added to the design, so that the warmth of the sleeping bag is more perfect.

Second, anti -clip lining

Regardless of the full or semi -open sleeping bag, a zipper needs to be packed, and when the sleeping bag is switched, the zipper often bits the fabric. It is very inconvenient to use. If it is not good, it will bite the fabric or break the zipper.In order to solve the contradiction of zipper bite cloth, the anti -clip lining was added.

Third, double head zipper

Early Sleeping bags are usually single -head zippers, which are opened from top to bottom. Closing from the bottom up makes the temperature in the lower part of the sleeping bag cannot be adjusted.Randomly adjust the volume of the upper and lower parts to adjust the temperature in the sleeping bag.

Fourth, single and double slice

Sleeping bags can also be divided into single -layer slices or double -layer slices. Due to the softness of double -layer slices and better warmth, the high -end Sleeping bags are generally used in double slices.
