Did you ever at some point say, "I'm done with leather. It's just kydex from here on out." Kydex seems to be growing in popularity, and there is always the option of kydex sheaths that have leather belt loops or frogs. Did you at some point stop making sheaths and just sell the knives? Did you at some point stop making sheaths, and outsource all your sheaths to a specialist? I am just about ready to give up on leather. I like the look and feel of leather, but it seems like there is no end to skill building and better tools and better materials, incurring more cost, for this craft. I don't have the money for a leather sewing machine, so it might be better to leave it to the specialists.
