Abstract
A sharpening apparatus with substantially rigid sharpening wheels disposed substantially fixedly on a rotatable drive shaft. An edge of a blade inserted in a slot in the apparatus comes into contact with a sharpening surface on a sharpening wheel. A sliding block associated with that sharpening surface slidably yields to accommodate the inserted blade and applies a force on the blade towards the sharpening surface. The user may selectively adjust force on the blade to achieve more or less sharpening of the edge of the blade. The plurality of sharpening surfaces can offer different levels or degrees of sharpening.
