An agricultural version, commonly known as either a brush-axe or bush-axe, is readily available in rural hardware and farm-supply stores in the United States today, and is available in the United Kingdom as a 'long bill'. It has a handle, and a head. It is extremely useful for clearing undergrowth and unwanted hedgerows. Both the concave and convex edges may be sharpened edges, but spear-points and back-hooks are not available. Expertly used, the brush-axe can fell a tree with a single blow. Inexpertly used, it can pose a grave danger of accidental maiming to those standing nearby.
