400 bucks is about exactly enough for a busse FFBM. or, if you can wait a couple weeks, you can see what's coming up in the next ganzaa.
or you could get a nice HI khurk, and a koster bushcraft. that's one hell of a combo.
or keep your eyes on the knifemakers' knives for sale forum, neat stuff drops in there all the time.
or you could get a spydie rock salt, which will never rust, even if it isn't as much of a chopper as you might be looking for.
or, or, or...
good luck with your decision!
