Irwin 2078611 12-inch Metric Quick-Adjusting Wrench Irwin 2078611 12-inch Metric Quick-Adjusting Wrench

Pros: It's a wrench that is easy to adjust. It's an ADJUSTABLE crescent wrench. It only needs one hand to adjust. It's the "better mousetrap" version of adjustable crescent wrenches. It comes with either SAE or Metric markings scaled on the side of the wrench so you can tell what size fastener you're trying to use this on.

Cons: It's still an adjustable crescent wrench and it still has the same failings of any other adjustable wrench as far as turning nuts and bolts goes. My Dad used to call adjustable wrenches "Polish socket sets" (as in Poland, not as in buffing material). There's a reason he said that- Adjustable wrenches are prone to rounding off nuts and bolt heads making them useless to real crescent wrenches and necessitating the use of a vise-grip. Especially those that are difficult to turn in the first place. This one is no different, it's just more bulky than a real, fixed crescent wrench- but easier to adjust with one hand than the standard type of adjustable wrench

It would have been just as easy for this company to put Metric scale markings on one side of the jaws and SAE on the other side and call it "universal". I guess they're no smarter than some of the people making a big deal about this being a "Metric" wrench.

Other Thoughts: The only thing that makes this a "metric" wrench as opposed to an SAE wrench is the marking on the side of the fixed jaw that tells you what size it's set at. That's all. It will fit anything you can get it around and tighten it up on. However, if you fit it on an SAE nut or bolt and look at the scale engraved on the side of the wrench it will not tell you which REAL SAE crescent wrench or socket you need because it's graduated in metric units not SAE. That is the only REAL advantage of having those graduations engraved on the wrench, so you don't try 3 or 4 crescent wrenches or sockets before you find the one that fits.

That's what makes this wrench METRIC and not SAE.

Otherwise, it's an adjustable crescent wrench and I'm sure all the genius mechanics commenting on Metric vs. SAE are smart enough to already know that. Or not, you pick.

Pros: Good quality tool, it is metric because of the adjusting mechanism, not because it is adjustable. It adjusts in metric increments not w/ a screw mechanism.

Cons: no cons

Other Thoughts: Has a metric mm scale on the side for reference. The SAE wrench adjusts in inch increments, the metric adjusts in mm increments.

Pros: It's adjustable, so I can use it on SOME bolts.

Cons: It doesn't work on Metric Allen and Torx bolts.

Other Thoughts: I'm originally from Canada, and I've seen fake Metric wrenches, and this is just a fake. If this was a TRUE Metric wrench, wouldn't be a "100mm Adjustable Wrench"?

Pros: it's an adjustable wrench.

Cons: it,s still an adjustable wrench.

Other Thoughts: A metric adjustable wrench? its adjustable, what difference does it make if it,s metric or standard? Hope they run a deal on a left handed screwdriver to go with this.

Pros: Ok so this is a first, a metric Adjustable wrench? wow go figure, I should have came up with that Idea but I guess I'm just "technically" challenged.

Cons: Won't work on SAE bolts or nuts ( but I already new that)

Other Thoughts: Wanna buy one of my metric hammers?
