Where are U in the Woodworking World?

I bought this hoping that it would serve my purpose without spending $80 on a "professional" square. For all of my life, I've had different kinds of squares available to me but, I guess it wasn't until I needed one of my projects to be "spot on" that I realized nothing I had was good enough. I've always worked with wood but, I never really crafted anything that I cared about being "square" square. Not to mention that I "assumed" all squares were SQUARE. Well, that's a croc. They are not! I didn't expect this combo square to be perfect but, so far I'm well pleased with it's accuracy. I don't have a caliper to check it but, from the checks I've made it seems to be fine and so far, square enough for my application. I would buy it again. I'd say that for the money, it's worth a try.

Square and more accurate than expected

Honestly I don't think I have ever been happier with a tool purchase before. I was expecting a blade that was parallel on both sides, measured customary measurements to 1/16", and a body I needed to file the lower guide on to make it parallel. That's a fairly low bar, but at this price point I think it's the best you can reasonably expect. I got a square that's actually square to .5mm over 250mm out of the package and has a 1/16" scale on one side and 1/32" and 1mm scales on the other. It may be that I just got super lucky on it being square, but unless you want to spend 10x as much it's actually pretty reasonable to think you're going to have to file the body. Essentially, you can pay a craftsman to clean it up or you can learn to do it yourself. I do wish the blade had the more precise measurements on both sides but given neither the pictures nor the description told me it had metric or 1/32" precision I'll happily take what I got.

well made and true

I purchased two Irwin combination squares- a 12" and a 6". Both squares are similar in construction with heavy cast Zinc handles with machined 90* and 45* surfaces, brass knurled locking nut , marking awl and bubble level cap. The rule is Stainless Steel and is clearly marked with finely etched and painted indicators in 1/8", 1/16",1/32" and Centimeter/milimeter scales. A simple but effective test for square is to mark a 90* line then flip the square and mark a line over the previous line. Any divergence in the lines would indicate that the tool is out of square. I was pleased to see both squares passed that test. I purchased two well reviewed (by some) similar sized combination squares from Amazon at more than twice the price of the Irwin squares and in minutes after taking them out of the box I knew they were junk. I returned them and took a chance on the much less expensive but well reviewed (by some) Irwin squares. I am VERY pleased as these Irwin squares are heavy, accurate, with great finish machining and made from materials that are virtually weatherproof. I would have happily spent double the price for tools of this quality

Great combo square: does what a $100 does, and does it well.

Very well made, feels relatively heavy and sturdy when you grab it. The ruler has very good etched markings. Both sides are used: one side Imperial and the other side is Metric. I was looking for a combination square for quite some time. Sure, the "expensive" models do look nice to show off but what the heck ... I wanted something functional without breaking the bank. This combo square is great and can do what the elite can do, no problems! I can't stress enough its qualities, so do yourself a favor and buy this one.

Easy to read very sharp edges, which for a combo square is a good thing.

Great combo square much nicer than my cheap harbor freight alternative. The only problem I had wasn't with the square but with Amazon shipping. They shipped the combination square which has sharp edges and points with another item without any form of protection from the square. So when I opened the packaged the square had cut through the coarboard box of the other item and it's contents spilled out. I did contact Amazon and they made it right.

METRIC! It has metric along one edge of one side!

Yep, I live in one of the last 3 countries that doesn't use the metric system (yet) and have trouble finding tools in metric for a reasonable price. I had nearly spent a bit more to get one that was metric on one side but figured this would work for now. I just got it today and will come back to finish this review once I've had a chance to use it and check for accuracy.

Great combination square for this price. Do not compare it with a $100 combination square

Great combination square for the price. I did the classic test drawing a line using the square, then turning the square and drawing the line in the same exact spot to check if it matches and the results are really good for this price. With pencils the lines match perfectly. Only with thinner lines I can see a little difference(maybe 1/64). I added pictures of the results. Do not compare this with a Starret. A better one a little more expensive would be the iGaging squares. But this one does a great job. Also, I didn't know it has a little marking pointer to make thin lines. Apparently every combination square has it.

Great square for the low cost

The Irwin combination square has a very rigid and solid feel and its weight is nice (my preference on weight). The square has inches/imperial depending on how you call it of (1/8",1/16",1/32") and metric (cm). The bubble gauge is a transparent yellow/green, so you'll be able to see through to your working surface if need be. There is a scribe pin on the bottom of the handle,looks like a brass colored bulb nice addition for crisp lines/markings (the scribe is not carbide but still works). Overall great square, meets the basics and then some.

Well built, sturdy tool. Absolutely love it.

Ordered this to help with (mainly) tile cutting during a recent bathroom reno, so pleased I ordered this one. The sliding nature allows you to select and lock in any measurement that in turn helps with marking your work, this single feature has helped me hundreds of times and saved me a ton of time. Also having the ability to mark at 45' as well as 90 have been essential for me. All in all, an absolutly fabulous tool for a fantastic price.

A nice combo square for the money!

I needed a decent woodworking combination square for my shop at my vacation home and gave this a try. I am very impressed with the overall quality for the money. I own Starrett brand ones 'back home' and this Irwin brand while not being quite as capable as those, you have to look at the cost comparison. For the money and for non-machinist type projects you can't go wrong.
