Frequently Asked Questions

What is a 36-inch steel straight edge used for?

A 36-inch (914 mm) steel straight edge covers yard-wide sheet, fabricated panels, frames and installation work in one pass. In leatherwork, it’s a strong choice for long straps, sizeable panels and gussets, and squaring hides.

What’s the difference between the 36″ and the 1000 mm?

Very little in length. 36 inches is 914 mm, so the 1000 mm metric version is 86 mm longer. Both have the same 53 × 3.25 mm carbon-steel body and the same accuracy of 0.001 inch per foot (0.084 mm per metre). Choose the one that matches the units you work in.

Can I check frames and panels with a 36-inch straight edge?

Yes, for practical checks. Lay the bevelled working edge against the frame or panel with a light behind it. Any visible gap shows bow or misalignment. Over the full yard, the edge is within 0.003 inch (0.076 mm) of true. Formal flatness inspection needs a calibrated DIN 874 straight edge.

Size check: is 36″ long enough?

It’s long enough for the long side of an A1 sheet (841 mm) in one pass.
It’s too short for the long side of an A0 sheet (1189 mm). For that, choose the Maun Steel Straight Edge Imperial 48″ (1701-048).
One size down is the Maun Steel Straight Edge Metric 800 mm (1700-800).
One size up is the Maun Steel Straight Edge Metric 1000 mm (1700-001).
