i made 1 on my first knife so the quality ain't great, but soak the bone ur using in bleach for about a week, then sit it in the sun to dry off for about a day. do not towel the bone dry or anything, just straight from bleach to sun. then i used muratic acid to eat the inside of the bone away, then i took a file roughly the same size as the tang of my knife and enlarged the inside of the bone to fit. drill a hole for a pine through knife and bone. then get some clear spray laquer and well spray it on lol. then put the hole in the bone about 1/4 full of epoxy, press onto handle, and slide pin in place. be carefull and make sure that you've widened the hole enough with the file beforehand or the bone will split. also you're gonna have to use atleast 6 coats of laquer (atleast when i did it) because the bone soaks it into it'self (same with some of the epoxy on the inside) luckily this makes it less fragile though and it stands up nicely to use (even if u split it )
