It's a new addition, so it's hard to say. My previous SAK was a Champ, and I used the metal file and scissors the most, but I always wanted a bit driver for the electronic maintenance that I do.
Well I'm a little biased because I'm the creator of it and it's still in development, but overall I like it. I am going to raise the handle length from 75mm to 100mm because I feel like I need that extra boost in leverage for any substantial prying task that requires a lot of force.
It shows in good detail how to make a particular type of shack with bundles of sticks :P
