>smooth, almost pen-like glide I have a Mitsubishi Hi-Uni 10B woodcase pencil, which is the only 10B rated pencil I could find. As you said, pencil hardness isn't standardized, but it's a very soft pencil, and it does feel smooth compared to other woodcase pencils. But it does not feel as smooth as a 0.5mm mechanical pencil with Pilot Neox 4B lead, which is the smoothest mechanical pencil lead I could find. The Mitsubishi does however write a little darker.
