ABSTRACT:
A hand-held sharpening tool is provided for sharpening sheet-like tools, such as plastic spreaders used to apply putty or plastic filler. A trimming blade is mounted in a central block, and a guide slot leading to the cutting edge is provided by upper and lower guide blocks connected to the blade mounting block. One of the guide blocks is spring loaded toward the other so as to yieldingly comply with the width of a spreader inserted into the guide slot for sharpening. A set of conveniently located set screws is provided to retain and adjust the trimming blade. The sharpening tool of the invention can be used to substantially prolong the life of plastic spreaders which would otherwise quickly become unusable.
