Reader Favorites: Vise-Grip Locking Wrenches

That, or when you really want to grip a fastener without any chance of slippage. I just used one today, and it totally saved my ass on a fuel line I was struggling with. I have them in all three sizes: 4″, 7″ and 10″.”

I prefer LockJaw pliers: http://www.lockjawpliers.com/features.html

The difference between these and lockjaws is that these will not damage the fastener.
These are one of the tools I asked about here:

I’ve since become very fond of the tool - it defeats channel locks when it comes down to the magnitude of sheer torque one is able to apply since you don’t need to worry about holding the jaws tight.

So you guys use these on brake lines and metal fuel lines?
I’d be scared to crush the fitting altogether, but if they can handle the ‘clamping’ and don’t slip (ever?) I’d be all over these.
Thanks for the post, defenitely on my list of ‘to need’.
