I highly second picking up a Sharpmaker as well, it'll teach you quite a bit about how to put an edge on almost anything. Even just starting out it managed to sharpen everything I had, in time you can try the fancier edges for the best fit. Your EDC is just the start, soon it'll make its way through your kitchen, tool box, garden shed, and into your friend's stuff as they go to you for touch-ups.
As for the knife itself...The Axis lock is an amazing little thing, you may find you appreciate it too much to give it up. Another Axis model with a different color handle or blade shape may fit your needs, but otherwise Spyderco will fit your needs nicely. If it were me starting out, I'd get by with a colored Delica, the green and gray models blend in with my wardrobe better. The Salt 1, Delica in absolutely rust-proof materials,is worth the investment if you want to swim/shower with the thing as some one suggested for a 24/7 EDC. The Delica floats around in a few handle colors, the Salt in yellow or low-profile black.
Everyone always jumps on the pink handle versions for their wives and girlfriends...And we always hear back later how they preferred the black models to begin with. I keep around a few tools in pink and purple, only because I always get them back when people borrow them, they don't want to be seen using them.
