Speed Skating Sharpening Course

The speed skating tutorial is as follows:

First, use a rough grindstone to polish it, and 8 characters will do. You can see the grain of the millstone from the blade; Then oil it with an oilstone (long, fine-grained) and start fine grinding, which is shaped like a figure of eight and grinds diagonally until the blade is bright and flat.

At this time, the metal burr on the blade side caused by grinding is concentrated on the blade side. If you don't treat it directly, it feels worse than not polishing it well.

Then be sure to clean the burr on the side with an oilstone, carefully clean the burr along the straight line of the blade, and clean both the inner and outer edges.

Finally, test the sharpness of the cutting edge with your fingernail, and you can easily scrape off the nail clippings, so the polishing is completed.

Correct posture: feet are frozen outside, legs are slightly bent, steady, and push the ice sideways. The body always moves with the side of the cold foot. When wrestling with bent legs, you can hold the ice with both hands, turn left with your right foot and turn right with your left foot.

Take turning left as an example, with your body facing the center of the circle, your right hand in front and your left hand behind. The left foot is the center of gravity, the right foot pushes the ice sideways, and then steps on the left side of the left foot from the front side of the left foot. After the next step, the center of gravity quickly shifts to the right foot, and the left foot is pushed to the ground left and right, taken out from the back of the right foot and placed next to the right foot.
