Just the idea of a sheath for the Sifu began to intrigue me when I read your post, so I pulled open my "stuff" drawer and pulled out an old Alessi Holsters "Ghost", which I use for small autos and revolvers. It a small leatherpouch, with Alessi's Nyclip belt clip and two "ears" on the body side to keep contents away from body/undershirt. Alessi's catalog says it works with "40 handguns, and still counting". Add one big knife. This is a rough side in, ambidexterous inside the waistband holster. It can be worn in front of or behind either hip, and the knife tilted to either side for crossdraw, etc. I haven't worn it enough to know what wear the G-10 will inflict on the leather, but suspect it will be minimal Thanks for stirring up the old grey matter - thought I'd pass it along.
BTW, my Sifu has the clip. Inserted in the holster for point up carry, it doesn't seem to interfere. In point down position, the clip is down into the holster and does drag when drawn. I don't know yet if this can be cured by practice, or if clip removal would be called for.
