I never used to carry a knife, but I got into the habit of stashing a SAK in the tool tray or tank bag of every motorcycle I rode anywhere out of town. Then I started using Leathermans, sometimes replacing the SAK, sometimes supplementing it. Then once in Mexico, the blade on the Leatherman let me down. I resolved that my first order of business was always to carry a good knife.
Most of the leatherboys drifted away, but most of the SAK’s are still here. I used to only like the red cellidor because of the toothpick and tweezers, but I found a better way to get plastic toothpicks, and my Leatherman Micra has tweezers, plus scissors that I prefer to the SAK variety. The only SAKs I carry are (usually) the Alox Electrician, a slim, useful 2-row knife, or the Alox Farmer, for when I go into the woods, just in case I might want the saw.
The Leatherman also suffers from the limited utility of the needle-nose pliers, so I always carry a 4” Channellock plier, which gets more use than any of my other pocket tools. There is a 4” Knipex, which is a better tool, but takes up a lot more room, so that one goes in my moto tool roll.
