Once again... living in my own personal vacuum of time and space I've never handled a spring-assist. I can say I'd prefer a flipper vs. a thumb stud, since I'm generally not a fan of the thumb stud opening. So I'm wondering now that I've experienced this and exhausted a search on Blade HQ... does Spyderco make a spring-assist knife? I'm not a fan of ZT knives... personally I feel like their ergos/asthetics are fat looking for a lack of better terms. That and they seem like a more mass-produced Strider knock-off. I could be way off on that though. I saw a couple Kershaws that were ok looking, but the price point immediately make me doubt they're of any quality. ($40-ish for a Cryo?). I'm not a knife snob (at least I don't think I am), but I feel like anything of reasonable quality is going to end up having a starting price of around $100. Again, I could be way off on this statement. Overall, though, none of the designs I saw really impressed me much.
