The 2-in-1 tool to make your work more accurate than everWith two accurate sides and endless uses, it's never been more affordable to invest in improving your work.

Based on customer requests, we took our Precision Straightedge and made it more versatile and less expensive, while maintaining all the accuracy you've come to expect from StewMac tools.

With this set of both sizes, you get 4 tools for the price of 2!

New design for the way you workWe've designed the middle of the straightedge so it's more comfortable to hold, more durable, and easier to pick up. To keep the weight down we made it out of industrial grade 6063 aluminum.

High quality, super accurate, and lower priceEach tool starts from a high quality extrusion, then we add a tough anodized finish to reduce wear, and finally precision mill each edge to exacting tolerances.

• Each one is personally inspected before leaving the factory.
• Guaranteed accuracy to +/- .0015" per foot
• Extruded 6063 aluminum with black anodized finish
• Each edge is precision ground after the tool is completed to ensure accuracy
