In my pocket? A Victorinox of one sort or another. Have been for the past 32 years. I get too much use out of the other tools on a SAK to go with just a straight knife. Heck, one time while cycling in Big Sur, I wound up taking apart the carburetor of a VW Bug with my SAK. Literally pulled a small moth out of the primary jet. Put it all back together and the previously stranded motorist was on his way.
