Got mine in and overall it's... weird. Like I kind of expected. Highlights:
- The detent isn't weak but it's not strong either. Strong enough to prevent shaking it out but it's a pretty uninspiring flipper. It works beautifully with the Spydiehole, which isn't a surprise. Spyderco takes the "multiple opening methods" thing seriously, but that often leads to a less than spectacular flipper.
- When flipping the knife, you have to make a very conscious effort to not follow through with your index finger into the lock area. It's not a great feeling if you don't. You sort of have to flip the knife by applying a sharp lightswitch-style force and then immediately retract your finger away from the spine of the knife.
- The ergos are strange; not uncomfortable in the sense of hotspots, just strange in how unconventional the handle shape is. Your hand sure has hell isn't going to slip onto the blade though!
Gotta get more experience with the knife but it certainly is of that lovable brand of wackiness you expect from Spyderco.
