All of the above are made from Aluminium but the Martinez 2-in-1 offers the added bonus of a Titanium blade.

All of these share a lot of the same features on the Metric versions:

  • Down the left hand side, you will find measurements which all have 5mm increments for scribe lines, so working parallel to your working surface.

  • There are also markings along the bottom of the squares so you are able to mark perpendicular lines.

  • You will find graduations down the outside of the square which are for marking up your angles. This will correspond with mitre saw settings. 

  • They also have a secondary scale for marking out hip & valley cuts. 

  • All of these also have vials set into them for marking out plum & level.

Each of the squares do have slightly unique features which may help picking between the 3.

The Trigjig offers an area to be used for your 1/3 birdsmouth which is on common UK timber sizes.

Martinez offers the Titanium heel and also has a couple of quick reference lines to give 22.5 degrees and 45 degrees quickly.


Squijig offers a nice scale along the shoulder of the square.
