This is the Hongdui HD38V “fully loaded” 600mm T-ruler with the protractor attachment, and the quality is on another level. The engraving is crystal clear, it feels properly premium, and I like the sliding stops with the V-slot because I can use a normal pencil or a mechanical pencil. If you care about precision (and the ability to calibrate), this one makes sense.
