are you asking if anyone makes sheaths for those particular knives? or are you asking if any benders currently have those three knives on hand and, as a result, would not need yours?
if it's the second, good luck, hope someone chimes in and can take care of ya.
if it's the first, there's (possibly) hundreds of us here that could make kydex sheaths for the knives you've mentioned.
check the sticky on Master list of sheathmakers. i haven't added my name to that list, yet, my website is still under construction and looks really awful :-( should have it back up to speed in a few daze.
