Has anybody got any good contacts for knife sheath making supplies? I've reshaped the handle on my knife and it no longer fits snuggly in the sheath. Unfortunately there isn't enough leather to reshape the existing. Ideally I want to make it in a Scandinavian style, as that's what it is!the overall length of the knife and handle is 235mm with a blade length of 100mm. Also has anybody got any good tips for cleaning / polishing the actual blade?
