Anyone carry a knife / multitool as part of their every day carry? I have a super generic Kobalt multitool that I've found very useful to have on me at all times. That being the case and recognizing a $15 multitools limitations, maybe to upgrade to some form of Leatherman. Any advice? Been debating between the Wave vs Free P4. Also looking at their K4 which is more of a pocketknife (so no pliers). Thoughts?
