Heya, Daizee. To me the Benchmade 154CM always feels sorta toothy, like the grain of the steel is large. I could never get it quite to that hair-popping edge on my Sharpmaker. Maybe it's just me, but I've had two Mini-Grips, two full-size Grips and an Onslaught and they all felt the same to me.
Spyderco's version feels (again, to me) closer to VG10: It's smoother on the sharpening rods and gets a finer edge. It feels very similar to VG10 but less likely to roll, if that makes any sense. VG10 itself is one of my favorite folding knife steels, along with Old Timer and Case's 1095 or Opinel's carbon steel.
I always figured that the Manix 2 was sorta the Spydie version of an Axis-lock-Benchmade. And I don't care for how small the Mini-Grip's handle is, either. A Delica feels better to me, despite the slab sides.
