If we're talking which of those specific knives, then I'd take the Randall wannabe because I have a ferro-rod, SAK (in my Mission Wallet with a Peak 1xAAA LED light, Leatherman Squirt and pieces of DR's PSP) and locking folder as EDC now. I'd go with the bigger blade just to have something for bigger jobs. The Randall Model 1 is a pretty solid knife, hopefully the Black Jack clone will also be a good piece of steel.
