My poncho is quite special, it gets me out of the wind and rain or off a cold wet floor when out and about and always slept under it until i got the hammock. the poncho still comes with me though.
My Nirex folder is a great friend, full of all sorts of crap that i would not leave at home.
My Compass is always in my pocket and i have never worked in degrees.
My folding saw, i have carried one for near on 20 years now and have never had the need for an axe and the closest i have got to an axe was in the jungle when a machete worked just fine. OK i know an axe has its use in the frozen north.
My knife, not because of the knife but because what i can do and make with it.
And my best bit of kit is my teaspoon, it has been all over the world with me, sitting in my pocket ready to be used. I have never had need for KFS whilst out and about.
