Review on 📏 Grizzly H2993 Precision Machinists Square Set (4-Piece) by Chad Gue

If you are a locksmith and try to use them for your work you will get fired because they are not SQUARE. I tested the set on myself. Two had significant burrs and dented outer edges. Most of them had corrosion, scratches and so much unevenly distributed oil that small patches of carbon deposits accumulated. The packaging, while reliable, was a nightmare to open. Spend a little more (or even less!) and get a better set than these. They look and function like they've already been heavily used by someone who didn't care.
