Folding knife (usually Browning Black Label Folding Tanto)
Small flashlight (it's a Field and Stream, not sure the model but it's pretty small and runs on a single AA which is hella-convenient)
Bic lighter (don't smoke anymore but still carry one always)
I'm looking to add a good multitool that won't take up too much room in my pocket but can supplement what I already carry.
I've heard it said that you shouldn't leave the house without a way to catch food, prepare food, and cook food. The knife can cover the first two (there's a river between my work and home that I could spearfish in) and the lighter covers the third. Don't have my concealed carry license yet but once I do I will be adding a pistol to the mix.
