Starrett K53M-300-S Carpenters Try Square for Woodworking – 300mm Metric Set Square

This square has to be the best value square on Amazon right now. I checked its square when it arrived and it is perfect. The rulers are properly calibrated off the respective inner and outer faces of the stock. The thin metal ruler arm of the square is straight not bent like many squares with long thin metal rulers. It feels very sturdy and I expect it to stay square for a long long time. It is made of good quality steel not aluminium so it will not get dented and bashed easily like the aluminium ones do. The length is very useful for general woodwork and also for checking/setting the squareness of flat pack furniture while assembling it. Highly recommended especially at this price!

I bought this as my old try square was not entirely square anymore. Firstly let me say that this is a big try square, for the price I was expecting something smaller but you certainly get your moneys worth. Secondly, yes the edges on the ruler can be sharp and pointy, but this isn't a toy it's a piece of equipment so as long as you treat it with due respect there shouldn't be an issue. If you don't like the edges then just file them down a bit. The structure seems to be fine and sturdy with no flex or movement between the two outside edges, it does 90 degree and 45 degree measurements easily.

Mine is definitely square, seems OK in general, but there are some very sharp edges that need removing, so the quality is a bit poor, but it's a tenner and it is indeed square, so all's good.

Good accurate piece of quality engineering.

The ruler is stainless steel, and the base is made of aluminium; as a skilled carpenter, this is my go-to tool. I've been purchasing their gadgets since slice bread. This instrument is extremely accurate, and the Starrett brand is well-known for its dependability. Brilliant value; a must-have in your tool collection. The measurement numbers are clearly visible in bold print and will not fade. Definitely recommend

Very impressed with my first 350 size starrett square, light weight, solid and perfectly square and for a reasonable price, so impressed that I ordered 200 and 250 sizes both for £7! and both of those are perfectly square too, genuinely more accurate than some engineering squares that I've bought and returned in the past. Not checked measurement scale for accuracy this is based just on using as a square

An ideal carpenters square for baking straight cuts in wood. I've already used this more than I thought I would and it's been spot on every time. For cutting short pieces of wood to marking out longer cuts it's been perfect. For short lengths of mood I can even use it to guide my jigsaw or circular saw. For the price you couldn't ask for better.

I got the 300mm and was very pleased with it. I then bought the 200mm and wasn’t so pleased. Out of the packing it was cut yourself rough and needed a bit of honing to get it serviceable. It’s square though and that’s the main thing. Starret seems to have hit the skids like many premium tool makers but at £8.50 it’s hard to righteously complain.
