US 2023/0286069 A1 · BLADE SHARPENER FOR OSCILLATING MULTI-TOOL SAWBLADES

Abstract

An apparatus and methods are provided for a sawblade sharpener for extending the operating life of oscillating multi-tool sawblades. The sawblade sharpener comprises a first blade that includes a multiplicity of cutting teeth. A second blade is pivotally coupled with the second blade and includes a multiplicity of cutting teeth. The cutting teeth are configured to shear off a dulled cutting edge from the sawblade and form a new cutting edge, thereby providing a sharpened sawblade. The cutting teeth may have a size and shape suitable for forming any of course cutting teeth, medium cutting teeth, fine cutting teeth, or very fine cutting teeth, and the like. The sawblade sharpener may be operated by hand, such as by squeezing handles coupled with the first and second blades or may be configured to be mounted onto a tabletop or workbench and operated by way of a lever.
