Review: Clearly one of the best small squares out there - Super handy size of this square makes it a must have around the wood shop. Love the white on black easy-read markings. The price is right and it seems to be a quality tool. Was going to pay the price for one of those fancy smaller squares, but glad I didn't. For what I would have paid, I could have three of these. Will definitely get another one to have as a spare.
Review: Nice mini square. - Good quality. A square is a square but it feels sturdy
