Frequently asked questions
How do I check if it is square?
Draw a line along one edge on a straight board, flip the square, and draw again. The two lines should overlap.
Is it metric or inch?
The title does not say. Check the scale in the photos.
Is it accurate enough for furniture?
Verify it first. Check it against a trusted engineer's square, and use the flip test with a pencil line before cutting expensive wood.
