How cool would it be if your tape measure actually stayed put without having to hold onto it? You could walk away from your work and not have to reposition the tape. This probably isn’t going to happen for woodworkers anytime soon — but if you work with ferromagnetic materials, there’s always the Magna Rule.
Marked in both Metric and inch scales, Motor Guard’s flexible magnetic ruler will stay in place on any magnetic surface, whether flat or curved. Several retailers claim these are made in the USA, and Motor Guard itself purports to be a supplier of high-quality US products.
You can purchase the Magna Rules in a set with 12″, 24″, and 36″ rules. Pricing for the three-pack starts around $20 before shipping.
