Picked up at a recent estate sale.

Nice clamp! Very handy for woodworking!

Very nice. I have seen so many types of vice-grips. Although, I think my boss may have the largest collection of them in the world 

I purchased three Vise-Grip pliers at this estate sale.  Two rusty 11R's and this 4SP.  Less than $4 total.  I didn't need them, but the price was right.
