Would hate to have to choose just one blade. Likely one of my Zero tolerance folders, or my Benchmade Bushcrafter. I dunno... any one of my TOPS 1095 blades would be fine to live with as well.
I guess I'd have to narrow my circumstances down... SHTF in town might pick my ZT 0300 heavy folder. Escape to the wilderness and I'd probably rather have the Bushcrafter. But the rrason that I have safes full of guns and knives is so I don't have to live with just one.
