Tired of having the steel blades of ordinary try squares getting rusted and messed up? Tired of having those blades getting nicks on the blades? I have, and am now using sturdy wooden try squares, safe, rugged and accurate. This is such a square. Made by a craftsman using a walnut handle, 2” wide, 3/4” thick and 9 1/2” long, this has a blade made of furniture grade mahogany the is 1/4” thick, nearly 3” wide and has an exposed inner edge of 12 1/2” and an exposed straight edge of 14 1/4” It is flat, square (there are 5 wood pins holding it to the handle), and makes no noise or damage when it bumps into something. Made by a craftsman it is a joy to use. Fine.
