re: epoxy
Idunno. I've got a Truper splitting axe that I use quite a bit, and the top of the epoxy has been cracked a long time without giving out. I've been using it hard for several months now, and still no wiggle in the handle. I've like it to loosen up so I can replace it with a wood handle, but it just won't give up.
On another note, my local Thiesen's has started stocking the Stihl pro splitting Maul. The head is shaped a lot like your Bond, but I sure like the price of the Bond better than $105 for the Stihl.
