Let's see. depending on the day I may have:

4 cell black Maglite
5" blade fixed blade Hibbensknife (martial arts/throwing knife)
4" Opinel wood handle folder.
4.5" cheapie tactical folder.
Whatever rifle I may be transporting between houses.

...yesterday was a special exception, I bought a Swiss StG-57 bayonet. 10" stainless steel blade, black composite handled badass.

I always carry a knife, usually the Hibbensknife fixed blade. I may post a pic later
