I get really geeky about different blade shapes...
I think a drop point or a nice clip ( with or without a swedge ) is my most preferred blade shape to use. I really like a Wharncliffe for slicing things on a hard backing, really detailed work, etc. A sheepsfoot is great for things like carving or cutting stuff with slack in it that flexes. Same with a spey blade, but I like the really long spey blades like on a Case Trapper where you have that very long straight run, and then the belly at the tip.
I think one of my favorite blade shapes ever is one like on the simple Buck 119. You see it quite a bit in various shapes and sizes ( the 110 is kind of similar ). The EDCs I like though typically have a drop point or a straight edge like a Wharncliffe, for ease for sharpening the tip. I tend to mess up and round off the tips of my clip points if I don't pay extra attention.
I really like the congress pattern though, since you get a ton of blade shapes in one knife... I have one that's like $13 from China, "Steel Warrior" or something, that has a nice clip, sheeps foot, pen blade and a coping blade.
