I took a survival class where they used Pukko's (sp) and battoning the blade (using a branch to hit the blade and drive it thru branches etc). I would question the strength of the tang if too much lightning is performed as I believe, stress fractures could form easily. For lightning I would suggest tapering the handle leaving more mass inside for strength.
Also my instructor said you needed to be careful with the holes being too close to the edge as in heat treating cracks could form more easily.
