ABSTRACT:
A tool adapted for renovating or conditioning skis by sharpening the bottom and side surfaces thereof and including an elongated body having a pair of spaced apart shaving strips extending in parallelism along its underneath side and a pair of depending shaving blocks near its opposite ends, the blocks being spaced apart a distance slightly greater than the maximum width of any ski to be renovated by proper use of the tool. A handle is secured to and arches over the upper side of the body so that by first grasping the handle, they manipulate the tool so as to cause the shaving strips to bear transversely across the ski bottom in overhanging fashion and the shaving blocks to straddle the sides of the ski, then applying unidirectional torque to the body in either direction so as to bring the shaving blocks into contact with the usual metal insert-like runners at the juncture regions between the bottom and side surfaces of the ski, and finally moving the tool back and forth lengthwise of the ski, both the bottom and outer side surfaces of the ski runners are worked upon while, at the same time, the flat bottom working surface of the ski is scraped to a condition of flatness. In a preferred form of the tool, the depending shaving blocks are freely rotatable and have spaced apart shaving edges that automatically seat against the outer side surfaces of the metal ski runners of the ski being renovated so that during either the forward or reverse stroke of the tool the trailing shaving edges are properly maintained against gouging.
