When I refer to using a set of Vice Grips as a last resort, I must stress whatever fastener I use it on is already buggered by a previous operator and is going to be replaced after it is finally removed.
I always find myself using VG's on stuff that others have butchered previously.
Cheers, BB.
PS. MF, I'm a Sidchrome / Snap-On kinda guy.
I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
