Also, keep in mind that the forum knife is obviously a Native 5. If you end up getting one, I'd say maybe consider selling your current Native, and pick up the S35VN PM2 sprint, they pop up fairly often on the secondary market. That way you could get both the PM2 and the Sage.
Ooh, also, maybe consider a BBS exclusive Domino in CTS-204P. The Domino is another fantastic knife, and that steel is among the best stainless steels available from the perspective of pure edge retention (being very similar to M390).
the product page for the 2015 Forum knife. I'm shocked these are still available. Remember to use the discount code FORUM2015 on checkout.
