Kydex and a leather strap with locking snap or a solid strap which I prefer. It would be a super combo, no matter the blade. I really was only posting mostly because everyone likes pics and I saw a big thread about a guy thinking of a giant knife or something called a smachet and the talk of a karambit. but I didn't want to intrude. Plus I hoped to post something to get the thoughts from our huge loss of RC. The link was going to be posted in the near future, something to think about.
