compared to previous technique...
below figure is an estimation based on feel and observation.
unfortunately, i don't have the scientific/precision equipments to do that.
1) surface smoothness improved by 2~3x (observation under microscope)
-micro bumps are no longer present
2) final polishing improved by 3~4x (observation under microscope)
-even the most difficult area to polish, are now equally polished as other area of the pen
-micro scratches almost non-existent, or minimal, compared to previous
symmetry v9.1 (prototype)
dodecagon symmetry (prototype)
century b&c mini (discontinued)
century custom (ebonite feed, modified to use platinum converter, discontinued)
*i think this is the older polishing method. noticeable difference in polish level can be seen.
i remember spending a lot of time with the older polishing method on this one, should be redone with new method.
b&c for gathered (old, discontinued)
both of them have textured surface below, that's why it isn't as smooth
