Self-sharpening knife tip

Abstract

A debarker knife tip may be utilized in a debarker to remove bark from logs that pass through the debarker. The debarker knife tip may include a self-sharpening knife tip as a result of a wear material that is utilized to form one or more layers of the wear material to provide self-sharpening effect. In use. a portion of the self-sharpening knife tip of the debarker knife at a first cutting edge of the wear material may deteriorate away exposing a second cutting edge due to the self-sharpening knife effect. This self-sharpening nature of the wear material allows for the debarker knife tip to remove bark from logs that pass through the debarker in a more consistent manner for a longer period of time over the usable life span of the debarker knife tip.
