Swiss Army knife
Yep same for me. The knife you can take anywhere without alarming people. Nicely made and always useful.
Should have gone after that callus a year ago! Amazing how such a tiny thing can aggravate.
But you're right about a knife alarming people. Years ago in another life I opened a similar knife to cut a cable and my boss literally jumped backward and exclaimed in fear. But he came from a place where, when someone pulls out a knife someone else usually gets stabbed.
