This is a question where you can ask five people and get seven opinions...
What should a woods SAK or multi have, IMHO:
At least one knife blade
Wood saw
Can opener
And if you carry a SAK, then a pair of pliers with wire cutters. Found hundred year old barbed wire the hard way and almost found a porcupine the same way.
