This came up on BladeForums, and is a new company established by two of the knifemakers there. I really like the D2 and ruggedness of this knife, but it would be nice to get the price down $50 or so.
The ability to customize is a plus though, but I'm not sure I'd need or want to swap out the handles, and I think I'd see that as a minus versus something I didn't have to worry about working loose.
I do like the kydex sheath though.
