It sounds like a SAK with scissors would be real handy to me. I was wondering which model you all would recommend?
If you're planning to pair it with your multitool, I recommend the Victorinox Explorer Plus as long as it isn't too thick for you to be comfortable carrying in your pocket. It has a nice set of tools that would compliment your multitool quite well in my opinion.
Tools I've found handy compliments to a multitool:
Scissors- I noted the usefulness of these in your multitool thread.
Maginfier- deciphering worn or poorly stamped part numbers or anything else that needs magnified.
The screwdrivers: The smaller SAK will fit in some tight spots a multitool won't. Nice, but you'll probably use the drivers on your Leatherman most of the time.
The small blade: Small, thin and slicey. As long as you keep it sharp it cuts like a laser. Great for detail work. Makes a passable scalpel for basic veterinary work.
Glasses screwdriver: Obviously has the potential to be either priceless or useless, depending on if you or someone you're close to wears glasses or sunglasses a lot.
Tweezers and straight pin: Sliver removal. Especially if it's from treated lumber or posts. I try to get the chemical soaked slivers out ASAP.
Toothpick: The hygiene potential of these for actually picking your teeth is hotly debated. Whichever side you come down on, they work well for cleaning lint, chaff, etc out of cell phone charging ports or headphone jacks without being hard or stiff enough to really hurt anything on the phone unless you really try to.
The pen: It's too small in diameter to be all that good a pen, but it works in a pinch.
Lots of great added functionality as far as I'm concerned. The only real drawback is the size. It doesn't bother me in pocket, but it's thicker than many like. Here's a pic next to a standard sized Bic for size comparison.
