Hello Dirtyjim.

I see how you are doing the work. the shorter tang is nice and elegant and as functional as any. The ones I have done come up over the nose of the comb and screw into the top of the comb like the tangs on some old Tennessee muzzleloaders, and also like the 'Baker tangs" on some doubles you see.
The extension over the top does nothing to add strength, but it's what the customers wanted.
