As far as SAKs go, I have found a new EDC tool in my Victorinox Midnite MiniChamp II.

It offers a red LED and a retractable pen in place of the usual tweezers and toothpick. The MiniChamp is the same length as the Classic or the Rambler, but is thicker.

It has many tools, but is small enough that no one will comment if you deploy it. The MiniChamp is almost toylike in its appearance, which is fine by me.
