cool chopoff. I've been thinking about trying one of those. I read somewhere it was designed for cutting insulation. I have a few of the fiddlebacks on imacasa blanks but haven't had a chance to try them out yet. My Condor Viking machete blade held up very well in wood. I mangled the belly hitting rocks in the dirt hard enough to fling sparks. It took down a 6" tree in my way in no time flat. The handles got loose, but I was really waling into that tree. much fun
