Review on 📊 53315 Test, Measure & Inspect for Increased Efficiency by Omar Svagera

I bought lots of these and sold my spares to contractors who asked how to get one. There is a simple addition to make this product perfect. 6 centerline marks to add to the injection mold. I usually heat up the blade and melt each of the center lines, and that's really all it takes. For even better visibility I add an extra layer of silver markers. See photos of the end result.
