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!
