I picked this up from a friend. I know it's a wrench of some type. Anyone know what it was used for?





Thanks

I don't know what that wrench is for, but someone from Vise Grip probably got their idea from those jaws!

Here is a similar wrench put out my Roebling steel co. The company that built the Brooklyn Bridge.

one of a selection of oil field wrenches. They get
quite a bit bigger than that.

Grand-dad had one like that hanging on his one-row two-horse McCormik corn cultivator in the late "60"s. his was longer and narrower then yours.

Dad had one that he used a lot. He called it the alligator wrench.

Looks like an earlier time version of a speed
wrench. I bought a couple at Sears, each one had
one size on each end but allowed you to swing the
opening around the nut or bolt head faster. Those pictured are better, will take more sizes thus, need less wrenches.

I have never used one, look like a good way to ruin bolts and nuts. I have always heard them called alligator wrenches.

Looks like it would be for the old square nuts/bolts.

Alligator wrench. I think that was one of the brand names and you can see why they'd use that name. I've had a couple, they never really worked all that great for me, but it's better than nothing.

Here's a big one, 2' long, about 15#. It has a 2.5" jaw opening.

agree with others "alligator" wrench.

better for nuts that aren't too tight - easy to use like a rachet - faster than getting an open end wrench back and forth at the right angle on the flats.

problem is - who here has ever seen a nut that wasn't on too tight?

When I was a youngster, 60 or so years ago, my dad bought me a used bike and the wrench you pictured came with the bike. It fit every nut and bolt on the bike.
