A sharpener for an ice screw with a tubular shank and a bit that includes a plurality of teeth, said sharpener comprising:
- a fixed sharpening support equipped with a sharpening element in the form of an elongate blade with two opposing substantially planar surfaces;
- and
- a positioning slide comprising two openings for inserting the tubular shank, each opening having centerline axes that enter the positioning slide on different sides of the substantially planar surfaces, one opening angularly oriented for sharpening a leading cutting face of a tooth of the bit, and the other opening angularly oriented for sharpening an angled flank face of the tooth of the bite at predefined angles with respect to the sharpening element, the slide being able to move in translation while aligned and guided by the fixed sharpening support astride the two opposite substantially planar surfaces of the sharpening element.
