My Endura 4 "Kreined" FFG in ZDP-189 mostly sits unused. It's strange to be honest. It slices like a pocket scalpel and takes a razor edge and holds it for quite a while. Despite the tip having broken off twice, it still feels too long and slim. For some odd reason, my BM 710-1 which is nearly identical in dimensions is my new favorite.
FRN simply doesn't "feel" as good as other materials like G10, titanium, and carbon fiber.
Still, I decided to chance a pre-order for the new Para 2's in S90V and CTS-20CP and see if my pocket likes them.
