Review on 🔲 High-Quality Steel Double Square by iGaging by Logan Broadnax

Not as good as hoped. The steel ruler graduations were legible and appear accurate for woodworking. The square is accurate when I compare it to known 90 degree angles. My biggest issue was with the roughness of the setup. I had trouble adjusting the ruler's lock and moving the ruler to a new position with one hand, presumably due to the roughness. Tried oil, didn't help. I hesitate to flatten the rule because it's the matte finish that makes the numbers so legible. I hope that the operation relieves the situation.
