Quality furniture construction is easier to accomplish with quality tools. Our new 6" Carpenters Square is just such a tool. It's a perfectly machined combination 90 and 45 with handles for a physical reference to the edge of the work piece. The blade is machined from cast and ground aluminum tool plate. This expensive material is utilized for its mechanical stability and tendency to maintain close tolerances after machining. By milling the blade from a single plate both angles are held to a much higher degree of precision than what's possible from stamped, molded or 2-pc tools. The handles are milled from solid bar stock and fastened to the body with high strength socket screws. Separating the handles from the blade ensures they can be recalibrated to the blade if knocked out of position. Anodized for durability and appearance, the Carpenters Square is also engraved with inch scale markings on the vertical leg. Made in U.S.A.
