I would like to make a suggestion for owners of WWII blades. When I got my first one about 20 years ago, I took it to a local sharpener who ruined it. The amount of side clearance between the teeth and the body is fairly tight, and the sharpener ground off too much. Now the blade is almost useless, as it burns everything badly. All it needed was a touch up.
I understand that some sharpeners are better than others, but my suggestion is to only send your blades to Forrest for resharpening. YMMV
