What is the hardness of a circular saw blade?
Solid HSS saw blades are heat treated and hardened to 64/65 HRC for ferrous cutting applications and 58/60 HRC for non-ferrous cutting applications. This high hardness gives the cutting edges of the teeth a high resistance to heat and wear.
Can you make a knife out of a skill saw blade?
Old saw blades are almost always made from high quality steel. … The blade is already the right hardness for holding an edge, so you don’t need to treat the steel to make it a good knife. However, blanks cut from the saw are sometimes a little too flexible, but you can work around (or with) it.
