The new Hooyman 10 is built just like the original Hooyman Saw. The Megabite™ blade uses a high carbon SK5 steel in a tapered blade design, combined with an impulse-hardened 4 edge tooth that has improved tooth geometry for unmatched cutting performance and a longer cutting life. I-beam aluminum construction, In-line design, and the positive locking extension system combine to give you incredible cutting stability - even at full extension.
