What style do you want it to be (traditional, modern, locking, slip-joint, natural or synthetic scales, etc.)?
What type of Damascus are you looking at (there's a lot of different steels marketed as "Damascus" but in fact are laminates, crappy steels mixed together, or even poorly welded steels that come apart and corrode)?
Are you wanting a custom-made knife or an off-the shelf model?
I am a knifemaker and do some work with Damascus, my photobucket below, I make my knives by hand from scratch, but know of these knives would make a good damascus folder. there are stainless damascus wit VG-10 cores.
