The 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. The lock-back blade folds down with a touch of a finger. The Hooyman 10ft folds down to just 28" so its easy to carry, easy to pack, and easy to store. It extends to a full 10ft.
