I don't care for mauls much, I'm faster with an axe. I mostly use the maul with wedges. I had a nice Craftsman 6lb maul, teflon coated with a fiberglass handle, which was great for when you get the log cracked but it's still holding. You could sink that in there without worrying about abrading the wooden handle, and it wouldn't get stuck. But I cracked the head and must look for another one now.
Same here, for garden-variety big-box or hardware-store mauls. Lousy head shape, and woeful metallurgy. Just cheap. Even as hammers, their heads are way too malleable. A cracked head is big problem in opposite direction.
After arrival here of an Austrian-made maul, I took a disc-grinder and redid some cheapie maul heads to mimic the Muller's shape. Much better performance. Night vs day. The metallurgy still sux, though. Don't hit nasties.
After busting up a couple of mountains of oak/ash/maple, the Muller maul looks same as new, except for an application of Danish oil to the handle. (No fanboy for fads here.)
