I'm wondering how many of those posting to this thread have those fixed blade knives within reach right now? If so, what do you do for a living? I know that if I walked into my corporate cube with a fixed blade knife - well, I'd get stopped by security. They don't even blink at the folder. Its just the reality of my life.
Certainly, if I go out camping or hiking, away from my usual day-to-day rut, I will bring a fixed blade along (Becker BK10), but that is heavy and less likely to follow me where ever I go.
I can't help but notice that the Benchmade Rant, SOF Field Knife, and Fallkniven knives are much lighter. Are they suitably strong for a primary field survival blade? For chopping and splitting?
