Whahoo. My dealer just called to say they got some more in, I will finally be able to compare an actual 0562CF. I will say of the most recent models, my 0452CF was the stiffest of the bunch. But it's a double edged sword. You need more detent strength to build up power to throw that long blade, but don't want it too tough and not activate smoothly when needed. After many hundred of flips, it's now what I would call absolutely perfect.
Now developing a blister on my thumb trying to break in a Spyder Chaparral. Any change in the pivot beyond just really tight caused side rubbing. So my only simple option is to work the tang against the spring/lock (it's a back lock). I'm probably at over 1000 partial openings, and 60-70 fully open lockups. It's much better, but not like the Spyder's I'm used to.
