Why should the kitchen knife handle, spatula handle, and kettle handle have a convex and concave pat

This increases the friction between the hand and the shank, reducing the risk of accidental injuries caused by hand slippage.

The main purpose of the knife handle is to prevent slippage and increase friction. The main reason for sharpening the blade is to save labor and time and improve efficiency. That is, the knife is sharp and easy to use.

1) The kitchen knife is very sharp, when the pressure is constant, reduce the force area to increase the pressure of the kitchen knife on the dish

2) The pattern on the tool handle is to increase the roughness of the contact surface to increase the friction between the hand and the tool handle when the pressure is constant

Therefore, the sharpness of the blade is made in order to reduce the force area and increase the pressure; The handle is often engraved with a pattern to roughen the contact surface and increase friction

A good kitchen knife should have at least the following aspects. First of all, the whole knife surface should be very smooth, without unevenness and potholes. In this way, the sharpness of the kitchen knife can be guaranteed.

Secondly, it depends on the thickness of the kitchen knife, the thickness of the back of the knife must be greater than the blade, and the thickness of the tip of the knife must be greater than the thickness of the handle. Such kitchen knives can be more durable. Then pay attention to the cutting edge, which must be neat and free of cracks.

A notched kitchen knife is certainly a difficult one to use. Finally, it depends on the knife handle, and the quality of the wood used to make the knife handle must be passed, so that it will not fall off easily.

You should also be careful not to mix kitchen knives for Western food with kitchen knives for Chinese food. Kitchen knives used to cook Western food are often relatively small, and if they are used for Chinese food, they are not only more time-consuming and laborious, but also prone to danger. With the above skills mastered, we also need to pay attention to our own mentality.

After all, holding a knife is a dangerous thing, so we must pay attention to our energy when cutting vegetables, and don't think half-heartedly about other things. There are also many times when people are angry, and they like to cut vegetables to vent their anger. This is also very dangerous.

Beware of not being angry, but hurting yourself.

This is a theory about the nature of friction after the concave and convex meshing theory. It was first proposed by the English scholar de Sazolius in 1734. He believed that the friction of two metals with a very bright surface would increase, which could be explained by the increase in the molecular gravitational force of two objects when their surfaces were in full contact.

In order to increase friction. Because the embossing pattern can reduce the slippage of some oils.

Those patterns are designed to increase friction between the hand and the handle, making it difficult for those to slip off.

The uneven pattern will cause the hand to rub and the force will not fall.

The main thing is to increase friction and prevent people from slipping when they grab the handle.

If there are no such bumpy patterns. If there is oil on your hands, it is easy to slip.

In order to prevent the handle from slipping, it is more stable to hold.

This allows you to hold the handle better.

Increase handle friction to prevent slipping.

The handle has a convex and concave pattern, which makes the contact surface rough and increases the friction.

I just got my game yesterday, and I remember that the back was written 35g

Isn't there anyone talking about the game?

It's not hard to see it in those storefronts at the entrance of Friendship New Village.

Other video game stores are opposite Xinhua Road Giant, as well as Xintiandi, all of which have large billboards, which are not difficult to find.
