As an architect I’ve always been picky about my writing tools.
As a draftsman, I started using 2H lead, but learned a lighter touch and transitioned to H lead for my line work. For my lettering I always used HB lead, which Staedtler Mars discontinued during that stint and caused a minor panic, but we bought enough to last me thorugh to leaving for graduate school. And yes Staedtler Mars was a better lead than Alvin.
I also have picked up a few fancy fountain pens over the years, but ultimately they were too scratchy and have not been used.
I appreciate the fine points of rollerball pens, but I don’t like the fact they can get cloggy.
And the micro fine points of razors are nice for about half a day until they get frayed under my heavy hand, at which point they are not at all pleasant to use.
But my tool of choice is the Papermate Flair pen. It’s a finely crafted writing tool that is cheap enough I can have copies all over the place and feel no pain when it runs out of ink or when one is lost. With a plethora of colors, I can make multiple layers of notes on a single sheet of paper. The felt tip runs smoothly on any type of paper. The point is fine enough to make good notes, but blunt enough to degrade gracefully. It is in short, my perfect pen.
