I beat the hell out of this thing today. It didn't do badly.
After numerous thrusts, throws, and chops, my target piece of plywood is on its last legs. My stand also picked up a bit of damage. I probably don't even need to mention it, but it performed very well on beer cans too. My chopping needs some work though.
Besides the usual stuff, I gave it the HI inspection, which it passed. The only real damage that occured:
- Rolled edge from chopping on concrete.
- Head came loose from shaft. (I doubt it will ever come off again now.)
- Entire blade bent slightly to the right.
The tip, surprisingly, held up just fine. The rolled edge was easily repaired by ironing it out with a chakma and grinding off the rough spots with a file. It's not as sharp as it was NIB but it's sharp enough for its job. (If I change my mind on this, the belt sander is always ready and this steel sharpens extremely easily.) For the bent blade, I clamped it in the vise and applied my body weight to the shaft, a bit at a time, until it was more or less straight. While it was in the vise I proceeded to remove the retaining screw and wail on the butt of the shaft with a 5 lb. sledge. If I ever need to remove the head from the shaft again, I suspect that I'll have to cut the shaft and burn out the stub.
The verdict? Lousy knife (too soft, poor ergonomics) but decent head for a polearm and worth the money. I'm happy with it. If it were symmetrical and double edged, and a millimeter or two thicker, I'd be extremely happy with it but it probably wouldn't be $20 any more.
As a bonus, the do-it-yourself stores around here stock similar handles, sans finish but sanded smooth with a proper taper on the end, for three bucks and change. They look quite nice after applying some stain and spar urethane.
Next project, when I get around to it: removing what's left of that butt ugly paint job and going with a bare metal finish.
