No one has mentioned the front edge of the chipbreaker, (if there is one).

These are always sold unfinished. We need;

Perfect fit to blade back.

Top surface polished and creating a sharp edge where it meets underside.

The angle of this top surface must not exceed 45 degrees at front.

Any hint of a square edge at the front is liable to cause choking.

Best wishes,
David
