But this is an opportunity to beg for anyone who sees or find a Sherpa model to snatch it up and send it to Uncle. Or at least take a bunch of good closeup pictures. The Sherpa style has a heavy style buttplate much like a cloven hoof on either side of the butt's center, and a central depression between them that the tang fits into and is held in place with a "Z" clip or spring of some kind.
Uncle has been searching for a Sherpa style khuk for years in any shape, to no avail. If one doesn't surface soon to be used as a pattern by the kamis, the Sherpa style may be lost forever. So please be on the lookout for one.
