Microtech DE Executive Scarab. Bought it back when I was young and had disposable income and wanted it for the novelty factor. Was not worth the money. It's not a bad knife, but was SO not a good use of the money I spent on it. Could have bought multiple knives for the price that would have gotten a lot more use. It's still really cool and all, but every time I look at it the Maine spendthrift in me cries a single tear.
I actually like that one quite a bit more than their other kukri models. Polypropylene doesn't transmit any more shock to the hand than wood (less, even) and it sound like you were landing your blows forward of the sweet spot. It's actually a PVC hard rubber handle on those, though, if I'm remembering right. It's not polypropylene, at the very least. My main issue with the handle is just that the checkered grip texturing is over-aggressive and hot-spot-producing unless you buff the points off it with some fine sandpaper.
