Jonathan’s Hot Take: This Curve Scriber and Marking Gauge may be one of the most versatile marking gauges on the market. On one side, it works like a wheel marking gauge for scribing lines off a parallel edge. Standard, but works like a charm (and my usual go-to). But the other side features two steel rollers that can be used to mark lines while referencing curved edges — whether concave or convex. There’s also a universal pencil holder that can hold almost any marking device you like. Pencils, pens, markers, dragon stone… you name it. Plus, it comes with a metal scribe pin. With all these options, you can reliably mark lines in a ton of different materials including wood, acrylic, glass, ceramic, metal, and more. I consider Hongdui to be one of the greatest tool manufacturers of our time — and this is no exception.
