FaithfullEngineers Steel Try Square 225mm (9in) – Precision Ground, Hardened Steel Blade, Accurate Marking, Measuring & Layout Tool for Metalworking & Woodworking

I've tested just how square this is using this flip method demonstrated by YouTuber Peter Millard in his Clamping squares video who can show you much better than I can describe. Check out that video and skip to 2.20... Amazon won't let me link to the video but go to Youtube and search 'peter millard clamping squares' it should be the top result.I'm satisfied my Faithful is perfectly square, see my results in the attached photo. Whatever square you decide to buy, it's always worth checking it is actually square, it's surprising how often they are not.I have a number of squares, smaller and larger than this 6 inch one but I was lacking one in this intermediate size. This size is perfect for testing if a table saw and mitre saw blade is set square, at least for my tools anyway.The only thing that lets it down is that or arrival it seemed to have a lot of very light scratches. However, I'm willing to forgive that given the low price. I will probably have this tool for a lifetime so it's bound to pick up a few scratches anyway.Ultimately it's a sturdy accurate square at a great price, I wouldn't hesitate to recommend it.

Have been using Faithful engineer's squares for years in various sizes when I bought a set of three years ago. Unfornately I lost my 6" square perhaps sweeped up with wood chippings so I had to order a new one.As per usual the square is 100% bang on accurate. It's sturdy, well made and also well finished. It has a bit of weight to it which gives it the reassuring confidence that it won't break or get damaged easily if dropped of your work bench which happens to me on a fairly regular basis.If you need an accurate well made square that will easily stand up to years of abuse and rough handling and still maintain it's accuracy then look no futher.Very happy with this purchase.

This square is square, apparently unlike every corner in my new build house.

I ordered one of these squares to assist in the building of a wooden boat kit where parts had to be joined at 90 deg. Some reviewers have stated that it's 'perfectly square'. It isn't, not when put against 2 which I know are. However for the model building purpose it is accurate enough. I have since ordered a 2nd one. The weight is useful in holding parts at an angle whilst the glue dries.

I bought 2 of these little squares, 1 for work and 1 for jobs around the house and garden.The type of person that uses a square is the type of person that has an expectation about that square and also a certain standard level of their own craftsmanship...You will be ok with this square; it's good enough.

Sometimes a normal size square is too big for the job at hand - especially for internal angles where larger square just won't fit. Not much to say about it, but it does the job perfectly.I just wanted a general purpose "small square". However Faithfull have a range of smaller squares like this one. If you have a specific application in mind it may be worth checking which size suits you best.Ruled edges would be a nice extra.

I got this as I do miniatures and wanted a way of making sure the sides of furniture, walls etc were straight. It’s perfect for me, just the right size for my projects.I have no idea if it’s true 90 angle as I only have a cutting board with lines on but it is definitely straighter than my eyes!

High quality tool, absolutely dead on 90 degrees both on the inside and the outside angles. I was able to verify the calibration of my mitre saw. Because of the small hight of this square, it easily fits alongside the blade of a standard mitre saw (216mm in my case) and also useful for extending a marking around all 4 sides of a bit of timber, such as a 2 by 4. Great value and highly recommended.
