Thanks for all your suggestions! They helped me make a decision that I think I'll be happy with.

I ended up going with the Delica. The price point, the slim profile, and the overall design were what convinced me. I also want to try the Emerson Wave feature -- not because I need to draw fast, but because it seems like fun. I really like the Doug mini, except that I already have two of its bigger cousins. Somehow CRKT knives and I never hit it off.

As for multitool, I already have one that I expect to travel with, but I want a blade that locks. It sounds like there may be some multitools that have locking blades under 3", but I want to hang on to my old buddy.
