My mom: Leatherman Micra and Classic SAK, both gifts from me. She likes the scissors to trim her nails and cut string and stuff..
Actually everyone in my family carries to some extent, but since I'm the youngest I don't suppose I get any credit for that.. My brother and I used to get each other knives for christmas. My sister carries a spyderco ladybug.
One of my friends carries a Spyderco Native that I loaned, then gave to her. She said she took it out this weekend and showed it to some of her other friends, who remarked, "wow, that's a big knife!" She said she thought that was funny, especially considering the collection of 15"-30" khukuris I have lying around my room.
Sold one of my co-workers the Benchmade mel pardue I accidentally scratched up, presumably he's carrying it now..
I gave one of my roommates a gerber multi-tool for her birthday, I'll probably get her a nice lightweight one-hander for Christmas. My other roommate is most likely getting a spydie endura since he can't stop playing with the broken one I have lying on our coffee table... of course, then he'll probably just start eyeing up my model 42...
Seems like Spydies make good "gateway drugs", in my experience...
