The precise adjustment possible with the single knob/bedbar design gives the necessary control to provide a continual self-sharpening action— thus maintaining sharp cutting edges, assuring good quality of cut, and greatly reducing the need for routine backlapping.
front edge to remove this burr, improved cutting can be obtained. After extended running, a ridge will eventually develop at both ends of the bedknife.
