Excellent work Andy, "Outstanding," as Steve says.:thumbup:
And that's high praise coming from an old leather pounder like myself who is rather particular about his leatherwork.:thumbup:
And I can testify to the quality of Sarge's sheaths as I have one of them laying here beside me with a very nice and very sharp cutting instrument safely ensconced in it.
Let me give y'all a couple of tips.
One - You *can wax* your own thread and therefore have different colored stitching if you so desire.
A pretty red stitch looks particularly fetching ensconced, there's that eight grade word again,

in a black sheath.
Stitching can go a long ways in embellishing your work without actually tooling it. Patterns such as the simple floral pattern on the Gangaola by HI fits the bill nicely, that is if I have the name right and it's still available from HI?
Edit:
You can also use regular mercerized cotton sewing thread when sewing leather. You just have to wax several pieces together in order to get a heavy enough thread for sewing heavy leathers together.
The multitude of colors generated by doing so is seemingly almost endless! :EEK:

Bear in mind it gets several shades darker when waxed.
Two - Think outside the sheath, so to speak, when designing them. Just because the YCS karda's come packaged one way in the scabbard doesn't mean that one of them can't be turned over so the handle protrudes the opposite way. I've done the top one that way on the YCSs I've had just to make it easier to draw.
The kardas on my original Foxy Folly were done back to back when Terry reworked the scabbard for mine.
It made for a nice even sheath carry on the back of the main scabbard.:thumbup:
