Take your favorite knife or knives out of the ones you already have. Use it/them a LOT and take notes on what you like and what you don't. Use up lots of paper or cardboard before you use any steel. Keep it simple.
Carey's message about designing your own woman has a lot of merit. Only you know what will "turn you on" so to speak.
EDIT: the easiest blade to grind is a Wharncliffe/sheepsfoot, in my opinion. Where the edge is straight all the way from ricasso to tip, and the spine curves down to meet the edge/tip. This gives you a pretty fine point for getting into things; in fact you can make it as pointy as you dang-well please by shaping the spine however you want. It's easy to grind because the edge is straight and you don't need to concern yourself with keeping a nice bevel along the "belly" of the blade.
Such a blade is really handy in everyday use like opening packages and whittling and peeling apples and cutting steaks, but not very good for skinning critters or stabbing things.
This type of design is also extremely effective at slashing through clothing and making people bleed, if you want to make a self-defense blade.
