Yep i had a Leatherman style until someone robbed me of it these days key ring duty is commonly taken up by a Leatherman style.
Also in my multi too arsenal
Leatherman prst II
Leatherman Squirt
Leatherman Wave
Gerber something or other
Ive had the prst II well over 15 years now, its having a well earned retirement and generally hangs about the house for odd jobs where i dont want to get my tool box out.
The Squirt lives in my Commuting bag along with a couple of handy bits and pieces.
The Wave i use in my Camelbak for longer rides.
The Gerber? well the least said about that the better.
