This hardened, high-carbon steel blade has two 10 long sharpened edges. When one edge of the blade wears out, the other side is still usable, which doubles blade life. This blade takes up a wider section of material for jobs where the floor comes up easily. Also works well for removal of adhesive residue and floor cleaning jobs. A sharp edge is ground to a 30 bevel on both sides. Works on Crain No. 700 or No. 710 stripper machines. Dimensions: 3 wide x 10 long x .079 thick.
