Why Are The Blades Of Skate Shoes So Sharp?

1. What are skates?

Skates, also known as skate shoes, are shoes worn when skating. Steel skates or pulleys are installed on the bottom of the shoes and boots.

In the early days, the skates of skate shoes were tied to the feet with leather straps. Later, skates were clipped or strapped to shoes. The skates of modern skates are then permanently or semi-permanently (removable bolts) fixed on the skates.

2. Are the blades of the skates sharp?

Skaters generally wear skates for skating. Their speed is so fast. In addition to their strong body and excellent technology, they also cannot do without skates. Many friends have heard that the skates on skates are very sharp. So the skates of skates have How sharp is it?

Some friends have heard that the ice blades of skate shoes can cut meat, but in fact the ice blades of skates are not so sharp. Generally, the thickness of ice blades is about 11 mm. Instead, ensure that the two sides are at a 90° right angle. If it is used to cut meat, it is quite tiring like cutting meat with the back of a kitchen knife.

However, this does not mean that the skates of the skates are not dangerous. The speed of the skaters is so fast that they fall off the track one day. The 1.1 mm thick blade can cut the skin instantly under the strong impact, cut off the blood vessels and tendons, and give Athletes cause great trauma. Therefore, speed skating (especially short track speed skating) has very strict rules, competition clothing

It has a certain anti-cut effect, and athletes will also pay special attention not to let themselves fall to avoid injury.

3. Why are the skates of skate shoes so sharp?

The blades on skates are so sharp they look dangerous, so why use such sharp blades?

In fact, the reason why the skates on skate shoes are so sharp is mainly to help players slide faster on the ice; under the condition of constant weight, the sharper the skates, the smaller the contact area with the ice surface and the higher the pressure. Large, ice above -36°C is composed of crystalline ice layer, amorphous ice crystal layer, ice-water mixture layer and liquid water layer from the inside to the outside. The ice-water mixture layer in the gel state is compacted, and the water in the mixture is precipitated due to the "syringe phenomenon", and the ice particles in the transition layer roll along the direction of the blade movement, and the compacted part below fills the defects of the crystallized ice layer , making the skates move more smoothly.
