    This square has some gravity built into it. made from steel thicker than all the other engineer squares I've seen, it feels as if it won't go out of square at the first sight of your tool shelf although you may have to knock back some sharp edges. 10/10 and don't drop it on your foot

    Solid square

    Very happy with this item, good solid weighty square which inspires precise marking out and also ideal for setting up machinery and track saw cuts.

    First class square

    As an engineer, I have always used precision engineers squares, but this item is a superb quality square, quite heavy, but reassuringly sturdy. Brilliant for my larger woodwork projects.
    Highly recommended.

    300mm square

    Nice large solid and heavy feels good quality. Would recommend

    A square to rely on.

    I didn’t realise how untrue all my old roofing squares were until I compared with this engineering square. Going from first fix roof construction etc. to cabinet and furniture making shows that a few mm here and there really do make a big difference.
    This tool is a reliable reference. Worth every penny.
