I have to second Blast on his endorsement of a multitool for EDC. In an urban setting I believe it is an excellent survival tool. Granted, none of the blades are going to replace a good fixed blade knife in a wilderness situation, but they are more than serviceable and the other tools compensate for any shortcomings. You mention that you have gone this long without a multitool, but i can attest that once you start carrying one it's amazing how often you will find yourself using it. The Wave, albeit heavy, has just about everything I need at work, around the house or running errands.

The Wave also includes a ballistic nylon sheath (I know that some come with a leather sheath) that has room for some additional items. For example, in the two elastic side pieces I have a Fisher Space pen and a small single AAA-cell flashlight. There is also a small pocket on the front of the sheath and the back on the inside. I used some electrical tape to strap down some REI stormproof matches and a pre-threaded needle (thread wrapped around) on an old credit card (the card allows the tape to be easily removed and provides a good backing to prevent the matches from breaking) and inserted that into the rear inside pouch. The front pocket (covered by the flap) has the match striker strip. Just a way to stow a little extra gear.

Doug's review mentions stashing the single AAA-cell flashlight

Just pulled out that cut down credit card to admire my handiwork and apparently I also taped four mini zip ties (length cut down) and taped those on there too.
