Abstract
A scissor sharpener has a recurved frame forming a U-shaped channel and an opening for receiving four fingers of a hand for grasping. A sharpening stone spans the channel at a predetermined angle to the adjacent surfaces of the frame. Surgical scissors can be wedged within the channel while their cutting edges are drawn over the stone for sharpening.
Claims8
A medical scissor sharpener comprising
- a frame having a perimeter with a recurved portion forming an open U-shaped channel bounded by a curved wall and an opposite wall, a portion of said curved wall curving upward and away from said opposite wall thereby forming a widened mouth leading into said open channel, and an aperture spaced from said channel, said aperture having a major diameter large enough to enable four fingers of a human hand to be received therein to enable gripping of the frame,
- and a sharpening stone mounted on said frame and having a longitudinal axis spanning said channel and projecting into said aperture at an acute angle relative to said aperture major diameter, the degree of curvature of said curved wall being such that when a scissor blade is inserted into said channel in engagement with said curved wall while its cutting edge is at the intersection of said sharpening stone and said opposite wall, the cutting edge of the scissor is in a plane tangential to a surface of said sharpening stone.
