Shocking quality
Worst scale ruler I have ever seen, unreadable numbers and lines, waste of money

Sharp lines, heavy weight, perfect execution.
An exceptional drafting tool. The solid aluminum core gives this triangular scale a commanding, premium weight in the hand—miles ahead of flimsy plastic alternatives. The matte black anodized finish provides a stark, high-contrast background for the laser-etched imperial markings, making it incredibly sharp and effortless to read under studio lights. The ridges are clean, the apexes are perfectly sharp, and it sits completely flush against the blueprint paper without slipping.

Works as intended
Works properly. Has some weight to it but convenient to hold paper down. Seems accurate enough.
