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 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
