Benefits of technology

[0009]Therefore, the objects of the invention are: to provide a sharpening kit for carpentry wood scrapers, including a burnisher, a block with variously aligned openings for slidingly receiving the burnisher and holding the rod at various selected angles relative to vertical, a file and a clamp; to provide such a kit wherein the burnisher is accessible to sharpen both linear edged scrapers and scrapers having curved edges, especially those having concave scraping edges; to provide such a kit that allows a user to both prepare or dress the scraper edge and then reshape and sharpen the e

Problems solved by technology

The edge may be originally factory formed; however, the edge becomes nicked and / or loses sharpness with usage and must be sharpened.
This functions to sharpen linear edges, but does not work well with curved edges.
Such devices are not able to sharpen curves that go inwardly or are concave in nature.
The prior art sharpeners do not allow unobstructed access to the burnisher by the piece being worked.

Abstract

A kit for sharpening scrapers includes a burnisher, a block, a file and a clamp. The block has a plurality of bores for receiving the burnisher that are aligned at different angles relative to each other. The block is held in place by the clamp with the block below an upper surface of the clamp and the burnisher extending above the clamp. The block also includes a recess for holding the file during preparation of the scraper for sharpening. The scraper can have a linear or curved scraping edge.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 879,753 filed Jan. 10, 2007.BACKGROUND OF THE INVENTION[0002]The present invention is directed to an apparatus for sharpening scrapers of the type that are used in the finishing of woodwork and, especially for scrapers with linear or non linear scraping edges commonly known as cabinet scrapers.[0003]Wood scrapers are tools that have been used by non commercial and commercial woodworkers for many years to finish wood surfaces of cabinets. Such scrapers are generally planar sheets of metal having at least one side where a scrapping edge is formed by biasing a side against a hardened material, especially at an angle, and forming a curl with a sharp edge. The edge extends outward and at varying angles from the plane of the scraper in accordance with the angle formed between the edge and the hardened material. The edge may be originally factory formed; however, the edge...
