This is a new sharpener for us. It was a customer request and we really like the idea of the oil and sharpener all in one. Thank you, customer! This sharpener features a tungsten-carbide edge, ribbed finger grip, and a red plastic handle with twist off oil dauber in the barrel of the grip used to lubricate the sharpened blade. This sharpener sharpens all types of non-scalloped or serrated cutting blades.
