Precision Protractor

I've not yet used it as I'm not up to that stage in my first project, however it looks well engineered and will help me centre the bridge (its first job) and hopefully do fancier things down the line. It's a lot lighter and less substantial than I was expecting.

Top-notch product, really good quality and at all that’s needed for Guitar Building

A phenomenal piece of kit. Nobody else makes any quite like this and believe you me, I searched a lot for any alternatives. This protractor is well made and worth the price. Not only for guitar building but especially for that purpose. It is just the right size and with all of the fiddly details that clearly were developed by someone for guitar making. It is honestly one of the most frequently spotted tools in YouTube videos after only the Shinto rasp. It is shocking that StewMac are not selling a competing product at 75% more. I was not even able to find a remotely similar tool in Japan. The all powerful center line yields many other lines and angles from wielding the Crimson Protractor!
