Abstract
A cutting blade for a clearing saw includes a plurality of teeth, with at least some of the teeth having a leading edge, a trailing edge, and a point in between the leading and trailing edges. The trailing edge can be hardened to a depth in the range 0.02-1.5 mm, and the leading edge may be left unhardened to provide a cutting blade with increased durability and efficiency, that can still be filed manually to remain sharp.
