Architect nib

An architect nib is a very specialized nib-point design going back to the days when architects actually sketched out their designs on paper. It is easiest to think of it as a reverse stub or italic nib. Whereas a stub nib is cut wide from left to right, and architect nib is cut for length up and down. The difference is that if you write a line from the top of a page to the bottom with a stub nib, it is a very broad/wide line. Using that same stub nib to write a straight line from left to right, it is a very thin line. An architect nib writes a really skinny line from the top of the page to the bottom, and it writes a very fat line horizontally. Authentic architect nibs from the 1920s into the 1960s are obscenely rare and expensive. Most people today get broad and BB nibs in modern pens and have a nib grinder custom make an architect nib.
