I carry an LM Charge TTi on person ALWAYS and carry a Benchmade RSK 1, as well, if far from home.

I am not a fan of HUGE fixed blades, so my choices there Cold Steel's SRK (in the car) and the "short" KA-BAR (in my bindle).

An Estwing all-steel camper's axe serves for heavier chopping duties, though I prefer SAWING where possible. I have used the "Pocket Chain Saw" quite a bit and give it high praise, by the way:

My recommendation for a really big blade is to go with a Kukri. Ontario, Ka-Bar and Cold Steel all have pretty robust offerings. For some interesting reads, see:
