Lee Valley Cabinetmaker's Rule
This rule has all the features that make a good cabinetmaker's rule.
It has machined edges, is accurate (including the first increment), has four different scales to suit a variety of requirements from checking lumber size to machinery set-up, and is easy to read in varying light conditions.
Reading from both the left and right, the scale subdivisions are in 8ths, 16ths, 32nds and 64ths, making it an extremely useful rule for woodworking.
At 1-1/8" wide by 12" long, it is an excellent rule at a good price. Guaranteed to be straight ±0.010" over its length.
