StewMac 2-in-1 Precision Straightedge

2-in-1 Precision Straightedge

The 2-in-1 tool to make your work more accurate than ever
With 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.

This gives you two tools for the price of one!

New design for the way you work
We'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 price
Each 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. Accuracy is guaranteed to +/- .0015" per foot.

Whether you're building a new instrument, repairing a vintage heirloom, setting up your shop tools, or tuning up your favorite daily player, this straightedge gives you the biggest bang for your buck possible.
