Currently our best bet is STR on these forums or this place:

It needs a bit of fitting for the Delica, Manix2, Para2, Stretch etc, but fits the Dragonfly, Viele I, Cricket etc. without any modifications.
Looks like this on a Para2:
I'd love it if Spyderco could make and sell the following clips (all uncoated):
Ti Military clip
Ti clip for the Stretch, Delica, Para2, Manix2 etc. normal shape
Ti clip for the Stretch, Delica, Para2, Manix2 etc. low rider
Ti Salt clip without coating (need one for my Matriarch)
Ti wire clip (might not be as easy)
I think it should be a decent way to make some extra money for Spyderco as well...
Please Sal...
