Abstract
A handheld tool used for conditioning and sharpening the blade of a scraping tool or like tool. The present invention tool includes a tool body that supports a file, a sharpening stone, a conditioning pin and a burnishing element. A plurality of slots are disposed within the tool, wherein each of the slots intersect the burnishing element at a different angle between 90.degree. and 75.degree.. The tool provides guiding surfaces that enable a blade to be properly worked against the file, the sharpening stone, and the conditioning pin. The step of burnishing the blade is accomplished by passing the blade through one of the slots formed in the tool. As a result, the labor and time needed to sharpen a blade is greatly reduced and the quality of the blade point is made more consistent.
