Got the g/f a Spyderco SS Dragonfly.
Pros:
- doesn't look particularly offensive (her friends think it's 'cute'; it's very small, shiny, and looks like some sort of jewelry)
- handles very well for its size (very secure in grip, works particularly well with smaller hands)
- has an opening hole (easier to hit than a thumbstud)
- is riveted together (low maintenance)
- is a lock-back (lock reliability, ease of maintenance)
- is lightweight, slim (slimmer than most (all?) FRN models), small (easily carried on the person, though this may not be a significant factor if it's clipped to a bag or in a side-pocket of a purse; however, the Dragonfly is still inobtrusive)
- has a very useful bladeshape for misc. tasks, along with a full flat grind that makes for an incredible cutter
- fairly low cost and is Spyderco quality and backed by their warranty, along with a very good stainless steel
Cons:
- the knife was pretty tight, and it took some practice to get it to where she could open and close it with ease, one-handed
- it's a quality, modern knife; it took a while to get all of the things we take for granted into her head regarding maintenance, usage, and knives in society.
She now carries it everywhere either IWB (when she has no pockets)/RFP with a little cell-phone strap as a lanyard. I lent her one of my tac knives to handle for a few weeks, just to get her used to handling and using knives; she ended up acknowledging that they are pretty useful things to have around, and I taught her the general rules regarding knife carry and use.
And now I have a very understanding g/f who recently bought me a Pacific Salt at a knife-shop in Kyoto.
On another note, there are probably other knives that fit the general criteria I was looking for, but the SS Dragonfly seemed the best fit overall. I also gave her a user 705; she still carries the Dragonfly over it. It was also a knife that I liked (and I get to handle it all the time now

); I bought it along with a few other knives for myself including a Calypso Jr.
