I recently made a handle on a Karesuando blade blank and behind the bolster put some leather and copper spacers.I used some 8-9 oz leather cut from a Tandy veg tanned tooling single shoulder and when shaping I kept finding voids or hollow spaces.I looked through Tandy's catalog and did not find any "heavy duty sole leather".What kind of leather do you that have experience with builing stacked leather handles recommend?I have seen pre cut leather discs on the knife building sites but would prefer to cut the tang holes myself.You can see where the voids are in this pic,they show up as dark spots where polishing media and wax has filled them.
