the dmle was originally advertised to have a penetrator tip but when it came out it did not have one and i remember at least one complaint but i cant remember who that was.
i think it was just a typo.the original dm is so thick that it pretty much needs a penetrator tip.if you look at the tip of the dmle you can see that their is no room for a penetrator tip imo.i think it would weaken the tip a lot.if you look at it you can see that it is pretty darn thin for a .25 thick blade.
hope this helps
