Stria-viivain

The brass feels substantial in my hand, and the folding mechanism clicks into place with a satisfying precision that makes drafting feel like a ritual. I've used it for a few sketches and the 45-degree stops are handy for quick angles without reaching for a protractor.

The 45-degree angle markings are etched cleanly enough to read at a glance, which saves me a step when laying out roof pitches. It folds flat into my apron pocket without snagging, and the brass has a warmth that makes drafting feel more like a ritual than a chore.

The brass has a nice heft and the folding action is smooth, so it feels like a proper drafting instrument. I love that I can lock it at 45 degrees for quick angle checks during model making.
