发明名称 Universal sharpener for ice skates
摘要 A small sharpening device for ice skates that is intended to be carried in a person's pocket, which can be adjusted to fit and to sharpen all existing ice skates having either concave or flat-ground blades. The sharpener has two side pieces that form a gap to fit around the ice skate blade and a central flexible grinding cylinder that as the sharpener is moved back and forth along the skate blade adjusts to and sharpens either concave shaped blades or flat-ground blades. The round central cylinder can be replaced when worn out or when a polygon shaped grinding cylinder is required for certain flat-ground blades. The adjustable, parallel sides prevent the sharpener from rocking from side to side as the device is moved back and forth along the blade.
