Machinists Square, 4"

The beam is perfectly square to the blade, and the notch at the inner corner kept sawdust from interfering with my measurement. Slides smoothly against my workpieces and feels substantial in the hand.

I had a tiny burr on the edge when it arrived, but a quick pass with a stone cleaned it up perfectly. The notch at the inside corner is a thoughtful touch that keeps debris from messing up my measurements.

The hardened tool steel feels incredibly solid in hand, and the blade length measurement from the inner edge is exactly what I needed for precise layout work. It's a simple but perfectly made tool.
