One of my favorite alpine locations served for as an evaluation site or "clinic" for this evaluation of several blades. It's high, it's remote, it's hard to get to, and it's wild, and it's the real dealio. The perfect schoolhouse for blades.
SAFETY NOTE: Using sharp and deadly tools in the wilderness can be dangerous. One missed swing and you could cut an artery up there. These videos will show imperative common sense safety measures to keep YOU safe from your own blades (and falling timber). Accidentally cutting YOURSELF is the biggest danger you will face in the woods.
