Honestly, I don't know. What is the most extreme use you envision for this kit? Making fuzz sticks for fire starting? Rebuilding civilization?

I carry a SAK for the multitool aspects and an Izula for more strenuous tasks. I'm not going to baton a 6 inch log with an Izula, but a 2 or 3 inch log is within the realm of possibility.
I like the RAT 1 as well, but haven't bought a 2 to compare. At the same price point, I'd look at the Zancudo as well. I see the 2 or Zancudo performing well as a general use, fuzz stick, whittling, food prep blade. I don't see any common folders surviving batoning more than once or twice. A $200 custom folder might, but we're not in that market.
