This clearing axe is designed specifically for cutting brush and small trees.
The 7" replaceable blade has 5-1/2" exposed for cutting. It cuts faster with less fatigue than an ordinary axe because it weighs only about 2 lb, including the handle, and because its balance makes it ideal to use one handed while holding brush aside.
The blade is sturdy yet, at just over 1/16" thick, has minimal wedging action, allowing deep penetration. The blade can be re-sharpened the same way as a regular axe.
