Frequently Asked Questions

What is a 24-inch steel straight edge used for?

The Maun Steel Straight Edge Imperial 24″ (1701-024) is an all-rounder for bench-sized sheet metal, medium gaskets, cover plates and fabricated parts. In leatherwork, it handles belts, handles, straps, bag panels and gussets. Two feet of reach finishes many everyday jobs in a single pass.

Is 24 inches the best all-round length?

For many workshops, yes: the Maun Steel Straight Edge Imperial 24″ (1701-024) is long enough for most bench jobs, yet easy to handle, store and hang on a standard tool board. If most of your work involves full sheets or long hides, a 36″ or 48″ will save you resets.

Should I buy a 24 inch or a 36 inch straight edge?

Go for the Maun Steel Straight Edge Imperial 24″ (1701-024) if your work fits within the long side of an A2 sheet (594 mm). Go for the 36″ if you’re working on yard-wide sheet or the long side of an A1 sheet (841 mm). Both have the same 53 × 3.25 mm body and the same accuracy per foot.

Can I use a 24-inch straight edge to check for bow?

Yes: the Maun Steel Straight Edge Imperial 24″ (1701-024) is made for practical checks. Place the bevelled working edge against the surface with a light behind it, and any visible gap shows bow or misalignment. Over 24 inches, the edge is within 0.002 inch (0.05 mm) of true. For inspection-grade flatness measurement, use a calibrated DIN 874 straight edge.

Is it a DIN 874 straight edge?

No, the Maun Steel Straight Edge Imperial 24″ (1701-024) isn’t made to a DIN 874 grade, because it’s a working straight edge for marking, cutting and everyday checks. If an inspection procedure calls for a particular grade, use a DIN 874 graded straight edge, and never cut against it.
