Since you’re new, I think you might not have seen my Crash Axe pics and video. You’d probably like them if you haven’t seen them. The Crash Axe Tomahawk was made by Swamp Rat, but is SR77 steel like the knives here. I used it to cut a big hole in a Horizon car hood. The Crash Axe is the same steel and thickness as the Dumpster Mutt, so it should be able to do the same thing. Here’s the link:
