Will it cut stuff better? Nope, sure won't. Not even a little.
But, I have found that I enjoy high end folders for what they are, and I'm good with that. I don't own any on the "higher end" of the high end spectrum, and probably never will, I think that $250-300 range is fine for me, but you never know.
Right now, I tote an 0561, and its been a good enough folder, that its replaced everything in my normal rotation of EDC. I back it up with a SAK Farmer, and a Fenix PD20. Good enough.
Will my 0561 cut open anything better than my Paramilitary, or Rake? Nope, but man, when that buttery smooth action swings in, and that tight lockbar snaps in place, and I get me a handful of that handle, ahhhhhhh, now that's the stuff, right there.
Rum, Sodomy, and the Lash.
