I used to carry a ColdSteel SRK in my backpack, but recently replaced that with a Becker Necker attached handle-down on my left shoulderstrap. I keep a Spyderco Native in my hiking shorts right front pocket. That's probably enough for me. The SRK now sits at home on the hikes.
I also have some old ColdSteel folder in my survival kit inside the pack (kit is stored in a 32oz Nalgene bottle). That folder is no longer made - I think it's called an "UltraLock" or something similar. It's a liner-lock, and as with all ColdSteel products, I don't know what the actual steel is. I could probably get rid of that extra folder in the kit ... I can't imagine ever forgetting my Spyderco or Becker when hiking ... but I like the idea of having everything I need inside a kit that I can move from pack to pack (even if double redundant) .
