How To: Filing Shoulders With Inside Radii For Tang To Ricasso Transitions

This technique helps distribute stress more evenly through the tang to blade transition area during heat treating etc.. This can be easily done with a round file, and a flat file with one blind side with rounded corners. An ordinary flat bastard file can be modified with a bench or belt grinder. The round file is for establishing the inside radius, and the flat file with the rounded blind side for flushing off and squaring up the tang to the ricasso angles without disturbing the inside radius.
