Clatchet, cleachet? Hatchcleaver?
I have about four "OLD" leaf spring sets, that I am saving for a time when I get my anvil, and a forge set up. Nice looking set up. Could hollow out the front a bit more to have a nice point on it, like the prow of the roman, or spartan war boats.

Very nice work, nifty, and quite handy piece of back pack tool!
