Hand squares are an important tool for a variety of
constructions. They are used to mark lines and check the accuracy of
specific degrees. The idea behind a hand square stems all the way
back to the 17th century when the “try square” was introduced in
China. Today, hand squares come in several varieties including the
try square, measuring square, and combination square.
• Woodworking tool used for marking and measuring a piece of wood.
• Measures the accuracy of a right angle (90 degrees).
• Made with a thin steel blade and a thicker stock, which is often
made of wood. Blades are made from fine steel, iron, or brass.
Stocks are made from rosewood, ebony, or other hardwoods.
• Comes in a range of sizes. Blade lengths varying from two to
twenty-four inches. Length depends upon the age of the tool and the
purpose of it.
• Also referred to as a "magic square," angle square, or protractor
• A durable triangular square used as a protractor and for scribing
lines at 45 and 90 degrees.
• One leg of the triangle has dimensions marked on its face in
• Another leg of the triangle has a raised ridge on the top and
bottom which allows it to be butted to the work piece.
• The longest side of the right triangle, also called the
hypotenuse, contains degrees that are marked on it. (zero to ninety)
These degrees help in measuring and marking miter cuts.
• Typically made of cast aluminum.
• Available in two sizes. The smaller size is seven inches on a side
(the hypotenuse is just below ten inches). The larger version is
twelve by twelve by seventeen inches.
• A woodworking tool used for multiple purposes.
• Used to lay out 45-degree and 90-degree angles.
• The stop is adjustable along the blade for use as a depth gauge.
• Can be used as a try square, to determine the degree of a square
piece of joint. It can also be used as a saw guide and as a level.
Cost will vary depending on the quality you are looking for. The
more expensive models also com equipped with a protractor head, for
marking and measuring angles, and a center head, for locating the
center of a circular or cylindrical work piece.
