Specific Blades for Toughbuilt Utility/Scrapper!
These blades fit other utility knives, but these are specifically designed to work with the Toughbuilt Utility/Scrapper combo knife. This knife requires a hole in the center of the blade in order to lock into the blade holder mechanism. Blades that don't have a hole in the center will not work.

As advertised
While most blades are standard these are not. I will say they are sharper than any of the other blades I have for utility knives..

Great value
I got a ToughBuilt combo utility/scraper knife at Lowe’s a while back. They appear to not have this product or the replacement blades anymore. These blades are unique to that knife. I purchased them here at a reasonable price and now my favorite utility knife has been saved from the trash.
