Great wrench!
One of the best adjustable wrenches I have found. Use it every day doing my oilfield trade. Opens wide to remove 1" plugs while being handy enough for smaller bolts/nuts. Quality is what you would expect from Klein.

Klein is what snap-on used to be - quality tools that don't let you down
This is a relatively heavy, well made, adjustable wrench. It lacks a positional lock but otherwise does everything you can reasonably expect from an adjustable wrench. The manufacturing precision is really what set this tool apart. Too often I find cheap wrenches which after a few uses the jaw faces are no longer parallel. Or there is too much slack and wobble in the sliding jaw. While I have owned wrenches which were even tighter in terms of precision movement, they cost more than twice as much (and are increasingly hard to find these days). The width of the fully opened jaw is also a stand-out feature - certainly wider than any 8 inch wrench in my toolbox. Overall the spanner feels 'chunky' and solid in my hand, with an excellent grip. I should add, I 'found' this brand after watching a youtube video from project farm - this youtuber reviews and tests (to destruction) a wide variety of tools and glues etc.. Klein came out as his preferred choice for people on a budget (aka me).
