I think that I would fit the description of a "female knife nut," although I tend to think of myself as just another person into knives.
To answer some of your questions, I have quite a few knives, some I carry more than others. A custom handled, BM Mini AFCK with file work and micarta scales, a Spyderco Mini micarta Calypso, a Spyderco Rookie and little Police necklace knife, a Spyderco 3/4 Jess Horn with white micarta scales, 2 BM Lepard Cubs, a Spyderco G-10 Harpy, a Spyderco Al Cricket, a BM Pardue 350, a 6 inch Katz Alley Cat, and a mini Smith and Wesson Swat. I would like to pick up a Viele as well, but the wallet is a little thin.
Personally, I prefer blade holes to thumb studs, and I can't stand thumb discs. I would also rather a liner lock to a lock back, but most Spydies don't come that way so I deal.
Most of my knives do not see very heavy use, although my Cricket needs to return to Spyderco to see the serration doctor. The mini Swat sees the most use at work, but the others will get used when I carry them and need to cut stuff (or just create an opportunity to cut stuff). I use my Harpy as a self defense knife, so it doesn't see much day to day use.
As far as price, if a knife fits my hand, I will probably get it. I may not pay over $200 for a custom piece because there are enough good production knives out there. I am also dating a custom knife maker so if I ever do need a custom knife I could just ask.
The size of a blade really does not matter to me as long as I can handle the knife comfortably. This is hard because I have very small hands. I hold my Rookie the same way that my boyfriend holds his Police model, for example. If the knife fits well, I will carry it, blade size is really not as important as fit.
I carry everyday because I enjoy it. I enjoy the beauty and function of the blades I carry.
