I am a service adviser for a Ford dealership, I used to be a mechanic in the same dealership and still carry the same things I did back then, a Delica 4 in back pocket, Victorinox Tinker in RF pocket, and Vic Classic on keyring. The Tinker sees the most use due to the tools and I use the blade for cutting up my apple for lunch every day, the Delica gets chosen for small cutting tasks cause its quick to deploy/undeploy, I use it everyday to cut open single serve coffee packets for the coffee maker.
