Knife tube

At the 1998 Winter Olympics in Nagano, Japan, technological advances gave speed skating a new boost with the introduction of the new CLAP ice skate. The traditional knife tube is called dead supporting knife by insiders, that is, the knife body is a fixed whole. The new CLAP is called a dislocated skate, where the front rest of the skate is hinged and the back rest can be separated from the skate. When the skater pushes the ice center of gravity forward, the back blade holder can be automatically separated from the skates, avoiding the friction of the tip of the "dead blade" to increase the sliding resistance, so as to extend the distance of pushing the ice, optimize the structure of pushing the ice action, strengthen the effect of pushing the ice, and improve the sliding speed. While the CLAP release skate is a great help for professional athletes, it's not for everyone. Beginners and children should always opt for the old CLAP when they're first learning to speed skate. It's more stable than the new CLAP skate, which makes you more likely to fall and fall. And even the dead support knife also has the points of speed sliding knife and short track knife, primary, knife do not choose wrong, speed sliding knife lower support more stable, short track knife support high, poor stability. Contact speed skating should start with a dead skate. Calp skates may cause backpedals. In the early stage, wearing the dead skate can cultivate the correct technology and is beneficial to the future technical development. The dead skate can change the effect of pushing the ice and improve the ice after pushing, especially in the curve sliding. Knife tube, you can choose domestic ice knife at the beginning. Quality, death have much difference, domestic ice skates, especially the dislocation type ice skates quality is relatively poor, but the price is low, the main difference lying in the dislocation between domestic and imported products, imports of dislocation type homemade ice skate is obviously better than the quality of ice skates, no matter from knife chooses steel tube, or hinge parts durability has good performance, but imports are expensive, ice skates It is suitable for amateurs and professional athletes who have a certain skiing foundation and need to improve their performance.

For beginners or children, due to lack of specialized training, the ankle joint strength is insufficient, upper shoulds not be too low, in terms of skates shoulds not be too soft, easy to stand on the upper is too low or too soft children, even stopped easily lead to ankle joint varus or valgus, if ankle joint strength is very poor, also need to rely on the knee joint force compensatory, knee joint of partial or partial, will appear Long coasting runs the risk of developing K, X and O legs in growing children. Also foot type skates by a longer production cycle (a pair of high quality foot type of speed skating shoes production cycle should be at least 3 months, carbon fiber epoxy resin layer will need at least 4 or more, each layer do need to curing fully before the next working procedure), children grow fast, foot type shoe mould and finished products produced during the feet long, Foot shoes are relatively small when they are made, so it is best for children to choose speed skating skates according to the number or the actual work model shoes. In the selection of knife tube as far as possible to choose the dead support knife, not only better safety, but also more conducive to the cultivation of correct technology, to lay a good foundation.

Lovers have certain basis, this kind of people can choose according to their own characteristics and economic ability of skates and knife, but no matter what kind of speed skating movement of people, choose the standard should be fit comfortable skates, skates isn't good for ankle wrap, upper and ankle gap is big, may cause pedal ice concentration, unstable support, the stability is not good, also easily lead to partial, The knife can't stand up. If you can skate technically and economically, choose foot shoes and imported CLAP ice blades.

The blades of professional speed skaters are like the guns of snipers. They attach great importance to every tiny link. The skates and blades will be carefully selected and fixed after a period of runnin. They rarely replace skates without equipment damage or technology changes. Now the skates of professional athletes are mostly foot-shaped shoes, and the manufacturers of foot-shaped shoes will adjust the details of skates appropriately according to the characteristics of athletes, such as the softness and hardness of the upper and the height. In terms of knife and tube, most athletes with outstanding strength in short distance will choose MAPLE knife, while those with long rhythm in middle and long distance will use VIKING knife. International brands of speed skating skates mainly include Maple, Viking, 4G, etc., from the Netherlands, and Marchese from the United States. In addition, in recent years, some brands of Korean skates have also been recognized by some athletes. The black Dragon ice blade is the most famous domestic ice blade and has the longest history.
