Empire Level 403 36-Inchx1-1/8-Inch Aluminum Straight Edge

Beware of Amazon shipping. They will pack this poorly in a triangular mailer tube which will get squashed in transit, bending the straight-edge. You will send it back, and get a replacement, and they will pack it exactly the same. You will not receieve a straight straight-edge. If you ever get a non-bent one, it will serve its purpose, but it's nothing fantastic.
