My parents lost part of a big tree a couple weeks ago in a storm and I worked most of yesterday morning chopping it up. Just to try out some new toys I took my Ontario 22 in Heavy Duty and Cold Steel Two Handed, 18 inch Bowie and Kukri machetes. I had reprofiled them all a little with an old Craftsman wet grinder, but none were really 'sharp'.
The Kukri machete was mostly useless. It would bite in a little, and would cut, but the molded in checkering on the handle was miserable to try to use (much as I suspected it would be). Might be great for killing a quick zombie or two, but not for this work.
The Bowie machete wasn't much better, but I didn't buy it for chopping wood and didn't expect it to do much. It was the sharpest of the bunch, and would dig in a little and cut ok, but didn't really do much. It was very hard to get chips flying with it. The handle transfered a lot of shock, and was very jarring to try to chop with. The sharpened clip also made me somewhat nervous (I kept seeing that edge come back at me out of the corner of my eye).
I had been using the Two Handed machete for a few months and generally been quite pleased with it for light stuff. It is light, balances pretty well, and is thin enough that it chops non woody plants very well even when pretty dull. On the tree it did ok, really acting more like a light hatchet. It would blow out little chunks nicely, but didn't have much weight to it so it was somewhat slow.
The Ontario Heavy Duty made me feel like I was in a Samurai movie. It would cleanly and easily slice through 1.5 - 1.75 inch branches with one good hit. 2-3 inches were done in 3 or 4 hits. Once I tried it I put all the others aside and used it to finish breaking down all the big branches. I still used the chainsaw on anything over 2-3 inches, but this thing just ate up all the smaller stuff. I can only imagine how one of these things with a proper convex edge on it cuts like.
I realize that none of these were really intended to chop up trees, but after Rita and Katrina I thought it would be good to know what they could do. The Ontario and Two Handed will be living in my truck toolbox, the Bowie will be at my g/f's apartment and I don't know what the heck that I am going to do with the Kukri machete. Maybe give it a dramatic overhaul, maybe just sell it off and buy a 12 inch Ontario.
