Uncle built saddles for a living for decades. Father also did some leather work. For carving you want a good quality vegetable tanned leather. Busted my third cell phone recently. So I built a case based on a holster. LOVE IT!
People spend hundreds on good knives and then lack a way to protect them. The sheaths they come with are either plastic or card stock and both are death on a good blade. I build with a compressed edge waxed runner that will not take the edge off.
A chef friend came over today looking for A cleaver sheath and a few knife sheaths. Was looking for a vintage look. We steamed, hammered, stretched and then dried the leather to get this effect.
Understand where you are coming from. But I'll give you an insight from a long term moderator.
We often see when a person is faced with a sick animal or emergency situation people often Skim the material rather than really reading it and respond from an emotional or reactionary perspective...
