The primary difference is that the EOD as two crimping holes (or whatever you call them) right behind the plier pivot. A large and small, used for crimping blasting caps and such. Could also be used for crimping wire connections. I have both and have used both extensively with nary a hiccup. My favorite story is that awhile back I was helping my son-in-law rebuild his fence (fell over during a storm). Well we were pulling nails out of the old boards. Some of the nail heads, being rusty and corroded, would not come out. So, I just cut them off flush with the wood with my trusty powerlock. Easy as pie. What is really neat, if you got a spare nickel is to cut the nickel in half with a power lock. Yes, they will do it. I know, I've done it.
