We have Land Surveyors Brush Axes, Surveyors Bush Axes, Surveyors Briar Blades all make quick work of clearing a line-of-sight through the thick brush and woods. Choose the style of axe that you prefer depending on the blade and handle style. Many have found that they prefer the thin double-edged axe for use when cutting through thinner material such as brush or briars and vines. The larger heavier axe if preferred if you're in an area that has thicker material such as small saplings or trees.
