Abstract
Abstract A ski-sharpening and surface-renovating unitary tool consisting of a strong, rigid, one-piece handle, having a grip at each end, and having three abrading surfaces, one longer abrading surface being placed just below and at right angles to two shorter abrading surfaces whereby the longer surface and at least one of the smaller surfaces can be simultaneously utilized to renovate the bottom surface of a ski and a metal edge of a ski, respectively. All of the scraping surfaces are of hard metal and the shorter surfaces are both detachably fixed to the longer surface for removal for sharpening.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
79 words
A unitary ski-renovating tool having a strong, rigid, onepiece handle with a grip at each end and a plurality of scraping surfaces of hard metal fixed on said handle, each with a cutting edge along each side thereof, said surfaces including two relatively short vertical scraping surfaces and one relatively long scraping surface normal to and mounted just below said relatively short scraping surface, said long surface being juxtaposed to said handle along the portion thereof between said grips.
Claim 2
Dependent Claim
79 words
A unitary ski-renovating tool having a strong, rigid, onepiece handle with a grip at each end and a plurality of scraping surfaces of hard metal fixed on said handle, each with a cutting edge along each side thereof, said surfaces including two relatively short vertical scraping surfaces and one relatively long scraping surface normal to and mounted just below said relatively short scraping surface, said long surface being juxtaposed to said handle along the portion thereof between said grips.
Claim 3
Dependent Claim
24 words
A ski-renovating tool as described in claim 1, wherein: said short scraping surfaces are detachable from said longer surface and handle for sharpening thereof.
Claim 4
Dependent Claim
51 words
A ski-renovating tool as described in claim 1, wherein at least one scraping surface is of a shallow, concave grooved configuration with said cutting edge at each end thereof and said long scraping surface includes a pair of seats, each for one of said short surfaces for preventing the twisting thereof.
Claim 5
Dependent Claim
113 words
A unitary ski-renovating tool comprising an elongated one-piece, strong, rigid handle having a pair of handle grips, each at an opposite end thereof and an intermediate portion between said grips, an elongated, ski bottom scraper extending along said intermediate portion of said handle and supported thereon, said scraper having hard metal cutting edges at each said thereof and a pair of ski, metal corner edge sharpeners, each extending normal to said ski bottom scraper at one of the opposite ends of said scraper and each forming an inside, right angular sharpening edge therewith said corner edge sharpeners being fixed against movement on said tool and spaced apart a predetermined distance from each other.
Claim 6
Dependent Claim
113 words
A unitary ski-renovating tool comprising an elongated one-piece, strong, rigid handle having a pair of handle grips, each at an opposite end thereof and an intermediate portion between said grips, an elongated, ski bottom scraper extending along said intermediate portion of said handle and supported thereon, said scraper having hard metal cutting edges at each said thereof and a pair of ski, metal corner edge sharpeners, each extending normal to said ski bottom scraper at one of the opposite ends of said scraper and each forming an inside, right angular sharpening edge therewith said corner edge sharpeners being fixed against movement on said tool and spaced apart a predetermined distance from each other.
Claim 7
Dependent Claim
41 words
A ski-renovating tool as specified in claim 4, wherein: said elongated ski bottom scraper and said pair of corner edge sharpeners are all separate but formed of the same hard metal material having the same shallow, concaVe groove cross sectional configuration.
Claim 8
Dependent Claim
40 words
A ski-renovating tool as specified in claim 4, wherein: said tool includes detachable threaded elements connecting said corner edge sharpeners through said bottom scraper to said handle, whereby all of said elements may be quickly detached for resharpening and reassembly.
Claim 9
Dependent Claim
53 words
A ski-renovating tool as specified in claim 4, wherein: said elongated ski bottom scraper includes a seat and shoulder at each said opposite end, and said corner edge sharpeners are each mounted within a seat and abutting a shoulder of said shank, whereby said corner edge sharpeners are fixed against twisting during use.
