It seems to me that with the wave and the microlights you don't need the SAK and flashlight. Any special reasons why you want to double up? (I double up on gear all the time. Especially the simple stuff.)

For all aroud use/abuse a AA or AAA Maglite is great. They're easy to carry and aquire batteries for jsut about anywhere. The extra bulb in the tailcap and solid aluminum housing make them extremely durable.

The E1 and E2 are great lights, but keep in mind the run time is only an hour to an hour and a half and the batteries can't be picked up at just anywhere.

The SAK is a unique breed of knife. Which model you choose all depends on what you want to do. How are you going to be using it? Is the cybertool worth the weight? If it is, then there you have it. If not, check out the tinker and super tinker. They're my favorite all around SAKs for EDC.

My EDC is as follows:

Benchmade 940 Osborne
Leatherman WAVE
Leatherman Micra (keyring)
Photon II (keyring)
Maglite AAA w/paracord lanyard
Strike anywhere matches in GI matchbox

Just somw thoughts. Let me know what you think.
