Take a look at the Becker Necker. This is a very small knife. The handle size may be a problem for you so try one before you buy. That said, I carry one EDC and hardly notice it. Very light, but with a nice thick "pry bar" blade which is typical of Beckers. Holds an edge very well. I carry it on the inside of my belt "behind" my palmtop belt case. The sheath just barely sticks out past the bottom of the palm case. About 3/4 of the handle is visible so it is not concealed.
I filled the usless (to me anyway) bottle opener and wire cutter hole with a high grade of "metal expoxy" and then did a stryker wrap on the handle. Added a finger lanyard and it became a very useful EDC knife. So far, none of the PHRASECENSOREDPOSTERSHOULDKNOWBETTER. have been the least bit nervous when I take it out in home depot or wal-mart to cut string or open a box etc.
Second warning: the handle is very small and may be a problem for you. It works for me though.
