Hey Ap Man I like your blades. A way of putting a handle on that Ive done before- weld a peice of threaded bar to the blade. Choose your wood or whatevers handy, drill hole to fit on threaded bar. Cut to length, make oval or any other shape plate for the back, weld nut on to fit threaded bar. Make small instep in wood to allow nut, screw on back bit and tighten. Voila- knive handle done. Its nice cause if its done right there are no visible rivets or anything. Ive used copper for the back- just braze a nut on. Hope you find this helpfull!
