Quite possibly the handiest, most versatile tool of this type you are ever likely to purchase. This combination square is small enough to be carried around in an apron back pocket. The 150mm rule lets you carry out many everyday marking out jobs.
This is a well made model: the blade is pearl chrome for maximum clarity and the stock is cast iron with an enamel finish, ground edges and faces. Calibrations are metric only, which saves confusion as both top and bottom of the rule have the same calibrations. The centre finder is a useful feature, not that often used but handy for those who turn, whether in wood or metal.
The set functions as a try square, 45° mitre square, rule, depth gauge, marking gauge and level etc.
