Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
149 words
An exfoliator disc for scraping and removing dead skin tissues comprising a thin, flat, circular metal blade, opposite side finger tip engageable grip portions generally centered relative to the blade, the peripheral edge of the blade including a continuous, laterially deflected scraping edge projecting laterally to only one side of said blade, said blade having a constant thickness and parallel flat surfaces extending to the deflected edge, said deflected scraping edge being formed when the blade is sheared from stock metal and having a lateral dimension in the same direction as the lateral deflection of the scraping edge that is substantially less than the thickness of the blade and a minute radial dimension measured along the radius of the disc, said deflected edge also tapering laterally to a feather edge with the peripheral side of the deflected edge forming with the peripheral edge of the blade a cylindrical surface.
Claim 2
Dependent Claim
