Noobie here.   My father gave me a few wrenches that belonged to his father.  I have identified this wrench but I haven't found any through google just like it.  It this somewhat rare or am I just looking in the wrong place.

It's common.
Commonly called a pipe wrench, for gripping round surfaces.
Plastic pipe will be the death of them.
But keep it.  You might fight off a home invader with it!

I have not seen many winged Crescent Stillson patern wrenches in my travels. As far as I know they are relatively hard to come by.

They are hard to find. Too bad that is not one of the ones needed to complete my Crescent display.

Thanks for the information.  I figured if I couldn't find one just like it using google, it must be somewhat rare.
