Zen-Wu Z-0 Straight Edge

The Z-0 was Zen-Wu's first straight edge: aluminum-magnesium alloy body with a brushed finish and a nano-titanium anti-fingerprint coating, one side with a relief notch for checking plane soles. Straightness tolerance under 12μm (< 0.5 thou). Will not rust or bend over time.

Discontinued. Its successor, the Z-1 Straight Edge, tightens tolerance to 0.007mm (under 0.3 thou), adds a hard-anodized finish, and gives you two working sides instead of one. The Z-0 remains available in limited stock.
