Mom pocket knife
When I was most recently in Seattle, my mom gave me her old Girl Scout knife: it's just been sitting in her jewelry box for the last 30+ years.
I sharpened the blade, and also -- since the "awl" blade was broken off, and thus un-usable -- I had my mom's first initial and maiden name (the period-appropriate surname) engraved on the remaining part of the blade.
As part of my everyday carry (Google "Everyday Carry" or "EDC" for some interesting websites), I carry a pocketknife and a multitool on my belt -- such that I always have a blade long enough to cut an apple in half, and pliers.
(That is: the knife must be long enough to reach the center of an apple. So sometimes I have a "regular-size" pocket knife, plus a mini-multitool; and other times I have a small pocket knife, and a "regular-size" multitool. In both instances, the multitool provides the pliers.)
