DuaLast blades are manufactured from a high carbon content alloy that can/may contaminate stainless steel with carbon. Therefore, DuaLast blades are not recommended for use on any stainless steel application that carbon migration cannot be tolerated.
The DuaLast blade was designed to be ‘refreshed’(sharpened), quickly, easily and without any special tools or operator skills. Every Scrape-N-Burr tool comes with instructions on how to put fresh edges on the blade. It is very important to follow the instructions to insure the through hardening process of the blade. Incorrect refreshing methods can cause the blade to dull easier or become brittle, resulting in blade chipping or cracking.
