Living in the city my fixed blades don't get too much use during the week.
But a pocket knife is "always" with me - like Pat said: "If I have my pants on"
I have quite a few to choose from and it depends on the occasion, of course, but I love them all
Large or small, old or new, plain Jane or custom...
This one is in my pocket today:
1983 Puma Jagdtaschenmesser 941 - rather large at 4-3/8"
