Faithfull Engineers Steel Try Square 150mm (6in) – 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.

good value; accurate and heavy

Top rate square for the cost. Very well made and good quality.

This is a nice square to use, it has a good solid feel about it and is well made. The base is nice and heavy and stands up on its own - ideal for checking table-saw\ band-saw blades for 90 degrees. I wipe mine over with DW40 before putting away in the clam-pack they came in to keep rust away. They do develop finger print marks but that is no big deal.

This is my 2nd purchase of this particular square. I have mislaid the 1st one and as its something I use so much I purchased a 2nd. I am sure the other one will turn up but at this price its no big deal. Used mainly for marking up box section and steel flat bar and also checking saw blade is true. It has a nice solid weighty feel to it and will provide many years of reliable service.

accurate....that's all that's needed.....well made

Really nice quality item. It really is worth the money and just holding it you know it's good. It comes oiled to prevent rust and you will need to oil it yourself from time to time.

Der mir gelieferte Faithfull Winkel ist sehr präzise. Auch für Profis geeignet. Für unter 20€ eine erstaunlich gute Qualität. Kaufempfehlung!

Ottimo accessorio ad un prezzo conveniente.

Gutes Material aber leider weit entfernt von 90° Winkel schade

Équerre solide en métal mais pas tout à fait d’équerre. Ce n’est pas rédhibitoire car c’est moins d’un millimètre mais faut le savoir. En même temps c’est le cas de nombreuses équerres même de grandes marques. C’est une question de chance. Après pour mon utilisation elle me convient parfaitement.
