Abstract
A thin rectangular blade of flat configuration has its two longer edges rolled or burnished to form alternatively usable sharpened edges. The blade is held in a structure which includes a handle having a concave surface against which the blade is adapted to be clamped by a convex clamping member in order to end the initially flat blade into an arcuate configuration such that the exposed scrapping edge is curved in order to reduce the likelihood that its edge portions will gouge a workpiece or the like. The blade is oriented at an angle with respect to the longitudinal axis of the handle, and the radius of curvature of the bent blade is approximately twice the length of its longer edges. A screw fastener holds the clamping member to the handle and clearance is provided for the reserve, or unused scraper edge of the blade when the blade is so clamped. In one version the screw fastener is threadably received in the handle and in another version, a wingnut is utilized on the screw fastener to achieve the clamping action.
