I have a ton of multi-tools. Usually two on me, key chain and pocket, one in the truck, one in wife's SUV, one in each BOB (2x), one in my desk I need to send to Leatherman for repair and probably a couple I left out.

I also sometimes carry a folder, usually on my belt. The folder does the job a multi-tool really isn't designed for. Like cutting heavy stuff. The folder has a more robust blade than the mut and I can control it better.
