FIELD: process engineering.
SUBSTANCE: invention relates to sharpeners and can be used for sharpening of elements that can move of snow and ice, for example, skis, skates and snowboards. Sharpener has sharpening surface to be displaced along the surface of sharpened element. Said surface has first and second sharpening surfaces to sharpen first and second angular ribs, particularly, skate blade. First and second sharpening surfaces are shifted sideway and displace relative to each other to adjust the side clearance to allow adaptation to skates blade depth range.
EFFECT: ease of sharpening of different-depth elements.
