I've posted this before, and since it's a Plier-Wrench and it's adjustable, it qualifies. It's patend date precedes Petersens Vise-Grip application.
Any tool galoots with ANY info about these, sound off. I'm not seeing any other pair like it.![]()
I have a Mastercraft version of that one....all along I was thinking if was chicom! I probably is made in china but it was cheap and works pretty good, for an adjustable. Any idea on COO of this one Monte?there is also "Atorn" + "Proxxon". I think there is a "Wurth" version too.

Diamond used / uses forges with die stamps to make their tools. Your point is well taken though. I worked in a foundry, and sometimes the molds would not be tightly closed and come apart just a bit to form what we called a "flash" or "flashing". In this case, the flashing results from the forge dies not cutting off the excess steel. If you look closely at both products, cast tools or forged, you will see a "parting line", unless it is ground off and polished. Most modern tools are finely finished and you see no evidence of how they were made. Thanks for the comment.They look like fresh out of a sand casting without having the overburden cleaned off yet. You see them after they have turned over so the overburden is behind the cast part now and not lying on top like when it was poured.
I want the Steinadler!!!! Really Fine example of a beautiful tool. Thanks for posting.Here are my main adjustables. I forgot the pipe wrenches though. The main highlight is the Steinadler with it's sliding center jaw that enables you to quickly switch from toothed jaw to smooth jaw. Pulling the handle out allows it to quickly slide the jaws to the nut and then lock it down. No turning a thumb screw required.

I use to have a set just like that except they where made by GM goodwrench. I LOVED them! Over the years all three have been lost or stolen and Ive been looking to replace them ever since..
The only composite adjustable like them I can find are the Blue-point's and the Greenlee's. Both are very expensive with the blue-points being the cheapest.
How much did that set run you?
Here is the GM Goodwrench composite adjustables. Luckily, I just picked them up for $22 shipped!!
I use to have this set years ago and have been looking ever since to replace them without having to pay the blue-point/greenlee price.

Adrien, the 10 inch Crescent may be quite rare. I have a 12" model. It was called the Crestolock and was marketed between 1958 and 1961 (ref. ads in Popular Mechanics). It was model number ACL110. After 1961, the ads only showed the standard Crescent without the slide lock. My mystery is that my 12" model does not have any model number forged into the handle, but was possibly re-issued this way in the late 1960's before Crescent moved from Jamestown to Sumter, South Carolina.Here's a few of my more "interesting" (to me) crescent-style wrenches. I left out the newer ones I have, which usually get the most use.
From top to bottom:
10" Crescent (this one is interesting to me because of the sliding lock for the adjustment screw)
10" Blue-Point by Snap-On
8" Crescent
8" J.H. Williams Superjustable
