heres an easy one for anyone to slap together,
great on the end of a breaker bar for those extra tough bolts, removing glass and windscreens, makes a great clamp in allmost any position, or even that little bit of extra thump to move something stubborn.
just remember you saw it here first :)
A brilliant multi purpose tool :D apparently, theres a beefed up version with a steelcap boot attatched too!!
