I don't even use my RC-4, it's in my bug out bag with an LM Juice S4. I do think it being on BOB duty is a credit to how much I trust it to perform under the worst conditions.
Fixed: Skookum Bush Tool Mk1 in CPM3V is my "go to" outdoors knife. I also, from time to time, use IJ puukkos and Woodsknife puukkos from Finland paired up with a folding saw or an axe. I simply like knives with the scandi grind, and with no choil or guard getting in my way better than the choil and flat ground style that predominates the ESEE line up.
Folders: Benchmade 610 is the usual EDC, paired with an alox SAK Farmer. I have also carried an Al Mar SERE 2000, a Benchmade Mini-Rukus Auto, a Buck 419, a custom Buck 110FG in BG-42 with nickel bolsters and jigged Asian water buffalo horn scales, a CRK Classic Sebenza, Spyderco Enduras of many different varieties, and a universe of SAKs and Leatherman tools.
In a maritime environment, my EDC is currently a Spyderco Pacific Salt in H1, and if I carry a fixed blade, it is a Spyderco Aqua Salt. Both are done in incorruptible H1 steel.
