mostly I have a 30 year old SAK (might be the executive model), one of the mid sized ones. It has tweezers, toothpick, scissors, electrical screwdriver and blades; basically everything that I need in a pinch and can't fetch a proper tool to do the job. I made a sheath to carry it horizontally on my belt, so it's unobtrusive in every situation but the closest hug. Otherwise I have one of my little higi's. I normally sell them in either O1 with a brass handle or pattern welded blade and brass handle, but since it's the only example of my work that I have on me in 'civilisation' mine has a pattern welded blade and mokume handle.
