I pulled the pics off the internet, but -
The Draw Point is by Mike Sastre, who seems to have slowed down, and has had some unhappy customers.
The Tanto was a Cutlery Shoppe exclusive from the 90's. You might want to drop him (Jeff Loffer) a line at the Cutleryshoppe.com website, and ask him who was helping him design the sheaths. For a while, they had a sheath division that was marvelous at these types of sheaths, I think it might of been Blade Tech that did the actual work.
Really though, I think most of the better kydex makers could do similar working off a photo. The trend now just seems to be heavier stuff. Also if you find a sheath that works otherwise, you can buy the Blade Tech "Pull Dot" kydex loops and Spyderco G clips separately.
