This reminds me of slide rule competitions. I remember being in a typewriter repair shop in Albuquerque and they had a small collection of antiquated equipment. One artifact was a slide rule that seemed like about the size of a very large bayonet. Even had a sheath, a hilt. It had what looked like katakana written on it. Maybe we should bring back slide rule competitions back.
