Q: What makes an edge rule different from a standard flat rule?
An edge rule saddles the workpiece with an L-shaped cross-section, so it stays registered against the edge while you mark or measure instead of sliding around like a flat rule.
Veritas Metric Edge Rules

The great advantage of this style of rule is that it saddles the edge of a workpiece, making it easy to hold accurately in position when measuring and marking layout lines.
Ours have an acute interior angle to ensure that they seat well, even over saw whiskers, and bevelled edges with etched graduations to minimize parallax errors. This design also simplifies transfer of perpendicular lines from face to edge, and is particularly convenient when holding and marking off dowel rod stock. The wide leg on the L-shaped cross-section is for face work, while the shorter leg is for narrow stock and edge work.
The metric set includes 150mm, 300mm and 450mm lengths. The smaller rules have faces with depths of 3/4" and 3/8"; the 450mm rule has face depths of 1" and 7/16". You can also use the rules on a flat surface – and, since the shape makes them much easier to pick up than a flat rule, you may find yourself reaching for them as your go-to rules. The 150mm rule is small enough to fit comfortably in a pocket.
Made in Canada from aluminum with a black anodized finish.
Rules are also available individually.

Yes, the rules work fine laid flat on a surface, and the L-shaped design makes them easier to pick up than a flat rule.
Use the shorter leg for narrow stock and edge work; the wider leg is meant for face work on broader surfaces.
We recommend the 150mm rule for pocket carry, since it's compact enough to keep on hand while the 300mm and 450mm rules stay at the bench for longer layout lines.
