It was a comparison I had been meaning to do, figured I'd share if anyone else finds useful. Kakuno EF is just a bit finer than a Micron 01. If an 01 is nominally 0.25mm, then perhaps EF is ~0.20mm. (but may vary depending on pen load pressure, as FPs do) Not shown, but also tested, a Kakuno F is roughly equivalent to a Micron 03. Of course these are all just eyeball measures, no 500x microscope or such involved, so YMMV
