Deadstock vintage ruling pen from Germany (HAFF). A precise stainless steel ruling pen that adjusts in 0.1mm increments via a dial. With its precise German nib and sharp black shaft, it truly resembles a work of art. In an era where analog records and cassette tapes are being re-evaluated, the beauty of hand-drawn ink lines may also be re-evaluated. The manufacturer, which was located in West Germany, is no longer in business, but they were a prestigious drafting company, comparable to Leica for cameras or Zeiss for binoculars and microscopes. The master craftsmen have already passed away, and it's impossible to recreate these now, no matter how hard one tries. This is a masterpiece, like a Stradivarius violin or a Steinway piano. After acquiring it, I kept it as a collection for appreciation without using it. Germany Vintage ruling pen HAFF236. Very rare and magnificent condition. An overseas collector and buyer are warm welcome, too.
