I'm a Klein man for 27 years. As stated above, CL for slip joint pliers and Cresent for adjustable.
Klein for screwdrivers and linemans. Channelocks for channelocks. Knipex for side cutters. Crescent for adjustables. Go with the brand that makes the best,
Wow, if you guys think Crescent makes the best adjustable wrenches, then I'll have some of what you two are smoking.
Even before Crescent went overseas their quality wasn't good, IMO. All the newer Crescent wrenches I've handled have super sloppy lower jaws.
As far as I know, only two companies still make adjustable wrenches in the US in decent quantities: Klein and Western Forge. Klein makes them in-house and pretty much any USA adjustable you find that isn't Klein will be made by Western Forge. WF makes private label wrenches for tons of brands. I think the WF wrenches are good quality and the couple Klein wrenches I've had seemed good quality.
I've read some posts claiming Apex Tools will still offer some Crescent brand wrenches that are USA made for industrial customers, but all the ones I see now in stores are Chinese.
There are also some Spanish companies making good quality adjustable wrenches. Irega and Irimo are the two that come to mind.
