Love my K4X. Great house/work knife & solid lock. Have EDCd it sometimes just because it's cool and badass, but I always end up coming back to something slimmer. I do wish there was something in the size of Gerber's Armbar Drive. I also have the T4 and its good, but the knife is a bit short for me and it is a tad thick. Still, really useful and all the tools lock and are sturdy as heck!
