Utilities in TF2

Utilities in TF2...Tools, not Paint/Tag/Duel/etc. Just "weapons", in common meaning.
Example is the Wrangler: you can't kill anybody directly with it, because you need Sentry.
Gunboats/Razorbck/DD-shield is another example, but you can't use it like a tool, holding it in your hands.
(Dispencer and Teleport enter/exit are tools too.)

Remember the game "Worms" and those utilities? It helps to understand what I do mean.
{Parachute/rope/etc.} It helps with movement, locomotion, etc.
