I carry these things all the time, even when I’m not in the workshop, it’s kind of like always having your weapon in the army, you would be nakid without them.
Funny you mention knife. I have a folding knife that resides in my pocket 100% of the day and it gets used very often for all kinds of stuff, but I don’t recall ever using it in the shop. Not even once except to break down cardboard boxes.
