Never ceases to amaze me how versatile this custom buckaroo style pocket knife #sheath is!
The style usually only holds a folding knife, and it suspends it in you pocket, a design developed and used by Southwest working cowboys in the early half of the last century.
This one was custom made for me to carry a Case split back whittler, and a custom pen I’d made, by a great craftsman by the name of Karel Koci, from the CZ republic (IIRC, it’s been a while).
A wonderful, generous, kind man, a pastor, a knife maker, leather worker, and craftsman of the highest degree…
I have unfortunately lost touch with him, the forums we were both on having disappeared from the Web several years ago..
Even having been made for a couple specific items, it always fits 90% of the knives I want to carry in it, not only holding them, but securely too! Love it!

You never know, you might cyber bump into him someday!
