Description: |
The angle of the knife blade to sharpener edge provides a scraping action. The adjustable feature allows for most of the hard sharpener material to be used.
Several household specialty tools incorporating this patent have been observed. Most have a variety of blade sharpeners; some incorporate glass cutters, etc. From ads in THE BILLBOARD, it appears APEX NOVELTY CO. (Chicago) may have been the source for these tools. |
