Here's the Achilles heel, the dreaded backside that haunts everyone but intrigues me.
thinking here. take just the center spline area from the handle, then, after fabing the handle from your material of choice, "square" the spline for a press and swedge fit into the handle, the handle fabbed to be able to do this. polish the handle and the spline "may" blend in ? it sounds harder than it may be to do. i can visualize what i just described, but i'm afraid i haven't conveyed the message very well.
