Abstract
A device for sharpening a cutting edge including a base an elongated slot that is dimensioned to permit free passage of a cutting blade therealong. At least one sharpening element is pivotally secured to the base near its upper end and extends across the slot at a predetermined angle. Preferably, two such sharpening elements are employed, intersecting at the slot so that a cutting edge moved along the slot will be sharpened on both sides during a single pass through the slot. The sharpening elements may be straight or curved and are always under a predetermined tension. This tension may be applied by either springs or counterweights.
