Speaking of multitools,
I see some of you listed the Leatherman Signal among your collection.

How would you judge it, from an outdoor use perspective?

Are the saw, sharpener, firestarter and whistle really useful (i.e. they can effectively stand in for their single-object conunterparts), or are they just gimmicks introduced by Leatherman to ride the whole survival-preparedness fad?

Thank you very much!
