Speed ​​skating blade is the abbreviation of speed skating ice skates. Speed ​​skating skates have long and narrow blades and are made of light alloy materials with good slipperiness, wear resistance and appropriate hardness. Ice skates are sewn with high-quality thick cowhide. The thickness of the ice skate blade should be uniform, the height of the two blades should be the same, the blade should be straight, without bumps and unevenness. The skates should be the same size as your shoes or one size larger. Shoes should feel comfortable on your feet, fit snugly but not be too tight. The tip of the knife is 8 to 9 cm longer than the tip of the shoe, and the heel is 5 to 6 cm longer than the heel. The blade of the left foot coincides with the longitudinal center line of the shoe, and the tip of the right foot is slightly to the left.

Speed ​​skating skates are equipment for ice athletes. Made of light alloy material with good smoothness, wear resistance and appropriate hardness. Mounted on the bottom of skates made of high quality rhino leather. There are speed skating skates, prescribed figure skates and free skating skates. Speed ​​skating blades are long and narrow, with uniform blade thickness. The tip of the blade is 8-9cm longer than the toe of the shoe, and the heel is 5-6cm longer than the heel of the shoe. The blade of the left foot coincides with the longitudinal center line of the shoe, and the tip of the right foot is slightly to the left. The blade of a figure skating knife has a slightly larger curvature, and the front teeth are slightly higher from the ice. The curvature of the free skate blade is slightly smaller and the front teeth are slightly lower to the ice. These two types of knives have a semicircular shallow groove under the blade, sharp blades on both sides, the blade head is located from the lowest tooth of the ice skate to the front edge of the sole, and the blade tail extends 1.5cm beyond the heel of the shoe. The front end of the ice skate is embedded slightly inside the center line of the bottom of the ice skate by one blade width.

Speed ​​skating knife grinding method

First, use a coarse grinding stone to grind in an 8-shaped pattern. You can see the traces of the grinding stone's grains on the blade. Then, use an oilstone (a long one with finer grains) to apply oil and start fine grinding in an 8-shaped and oblique direction. When the blade is bright and smooth, it is done. At this time, the metal burrs on the side of the blade caused by grinding are concentrated on the side of the blade. If you put it on ice directly without processing, it will feel worse than not grinding at all. Finally, be sure to use an oilstone to clean the burrs on the side, and carefully clean the burrs along the straight line of the blade. Clean both the inside and outside blades. Use your fingernails to test the sharpness of the blade. If you can easily scrape off the nail clippings, then the grinding is complete.

After reading this, everyone should have a certain understanding of speed skating blades. By understanding them, you can apply them to practice and practice speed skating better.
