I've owned both the SFNO-LE and the NMSFNO. I kept the NMSFNO. I think both are great but the latter has the rounded spine and a bit more length that, I think improve its utility at a very small weight penalty. In fact, the extra blade length shifts the balance point to make it a formidable chopper for its size yet, without sacrificing its quickness. It's my go to camping blade (for now).

I'm not trying to talk you out of a SFNOLE, but make sure you try the NM version as well. If I could justify it, I would have kept both.
