US 6,957,934 B2 · Wallboard rasp

Abstract

A wallboard rasp having an expanded metal blade mounted to a molded plastic handle. The handle is configured with a downwardly-opening receiving groove for receipt of an upwardly-curved perimeter portion of the blade. Sections of the blade's perimeter may be crimped or heat staked within the groove. The groove may be formed between a downwardly-projecting outer lip and one or more downwardly-projecting inner ribs. Where the blade is formed with a substantially planar central portion, the ribs may have substantially planar downwardly-facing surfaces against which the blade's central portion may be supported when mounted on the handle. The grip portion of the handle is configured as a contoured, upwardly-extending body having a base with opposite knurled inset surfaces and a convex top flanged surface with spaced-apart grip ribs.
