6英吋金屬尺 / 機械師用刻度（1/8、1/16、1/32、1/64）

The 64th markings are crisp and deep enough to read without glasses, which is a huge win for detailed work. Has a solid heft that keeps it from sliding around on the workpiece. Exactly what I needed for measuring small metal parts.

I was tired of squinting at cheap rulers, so this one’s a huge upgrade—the 64th marks are crisp and actually visible. It feels solid in hand, and the blackened engravings stay easy to read under my bench light.

The blackened engravings really stand out against the steel, so I can read the 64th marks without squinting even in poor light. It’s rigid and thin enough to slide into a notebook, and the 6-inch length handles most of my quick measurements perfectly.
