I've recently been hammering away making some mortise and tenon joints for my table build, and the chisel I am using at the moment is a Narex mortise chisel. No complains whatsoever about the blade, it's been working great. I am wondering, however, if it's possible to administer too great a beating to the handle? The top of the handle has a wide metal hoop with just a short piece of wood above it, and it's getting so flattened that it almost looks to be splintering. Is there a point of equilibrium where the top of the handle will more or less stay as is, or am I danger of smashing the top to smithereens? My mallet is a red oak one I made myself and I am wondering if the mallet itself is too hard for the handle.
