The Final SK USA 12" Adjustable Wrench... 

Definitely didn't talk too long, I'm enjoying learning about these old tools!

I buy lots of these old USA made crescent wrenches second hand. Never found any from SK, cool to see. Thanks for sharing.

The original Crescent brand switched from the wide jaw to the narrow jaw when they introduced their own steel alloy known as ‘Crestalloy’. I like the Jamestown version when working on plumbing, wider jaw holds copper fittings better. Like the Crestalloy for general mechanics for tighter access.

Great review, thanks. I've seen SK USA around; been using PROTOs for a while. They are tough and hard working (I have the set from 4" through 12" PROTOs).

Don't forget about dresser tools in the early 70's

🙀😿😾

Pittsburgh that's American right? SK will be like Milwaukee, a few tools made here, but owned by a chinese company.
