Finally, found somebody Steve, his name is Eric Arkuli(sp) but he owns www.arksknives.com and he deals a lot with Buck 110's. he on Facebook too. He told me his brother actually makes the sheaths for the 110's. Hope that helps you a little!
Steve, been checking around for a sheath maker per your post over in Forums and as of yet still have not found one. Could be lots are busy with shows, but hey we'll keep trying to find somebody for you. Don't give up! (If you did find somebody let me know) thanks much!
