Review: Great square and ruler set - Very good quality and value. The 30cm metric ruler is very well made and the rule is stainless? steel (not sure what grade of stainless as it is magnetic, so time will tell if it is susceptible corrosion) but much better than some which use aluminium. Markings on both sides of the ruler are good (appear to be laser etched) and the adjustable stop block is a very nice design, which includes a internal magnet that stops the rule for sliding off the rule unintentionally and aids positioning and setting the stop block. Obviously, the (~3mm) holes in the ruler are not really suitable for marking accurate parallel lines with a normal pen/pencil as the holes are round not diamond shape so allows too much opportunity for movement of the pen/pencil tip inside the hole. However, it can be used with care and an appropriate pen/pencil tip size. Also the ruler could be used to mark circles at 10mm size increments using 2 of the holes. The Metric only (so called 7 inch) ~18cm speed square is also very nice quality, made from aluminium alloy and does have V shaped marking points on one of the inset rulers, which is great for marking parallel lines at the preset alternating 5mm increments. Marking are clear/accurate and are etched into the surface not just painted. It also includes drill/hole size guides from 3 to 15mm, and a inset straight ruler and angle guide etc. This set is great quality and value. (the ruler can be purchased alone, but the set offers even greater value). Very happy with this ruler and square set, get one
Review: Great quality - Have been using these for over a year since my Stanley sliding square broke. Really good quality with helpful magnet and good size to fin in tool bag. Roofing square also good. Generally only used to square circular saw. Has outlasted a blade and cut miles of wood.

### ⭐⭐⭐⭐ A useful little measuring tool.
*by K***2 on 10 December 2025*

Firstly, I very much like the stop. However, I suspect some customers will probably want to pair it with a better quality ruler. To be fair my only gripe with the ruler provided is that for my less than perfect eyes the etching of the the deliniation lines is a little too feint. I note that they have all been etched deeply and crisply enough, so it's possible they just needed a little bit of black infilling. I managed to resolve the issue myself by running a black marker pen across all the lines and the numbering to make them stand out. I would say the product is definitely worth the cost for the stop alone, but that the ruler is still a nice addition.
