I made the hatchet in the attached photo roughly 14 years ago. The head is forged from 1" square 1018, the eye was slit-and-drifted by hand, and the cutting face is 1095 forge welded into a mouth that I hot chiseled into the body (as opposed to some constructions that lay the cutting bit next to the body for welding). Until today it had a handle in the same design as your 14" rigger's handle.
I just had the pleasure of making small modifications to your standard hatchet replacement handle and re-hanging my hatchet. The curve is just what I'd hoped for, and I much appreciate the inclusion of a wood wedge. It's soaking up a tray of boiled linseed oil and I cannot wait to get out to the woods to get chopping!
