original state: EF nib with approximately 1/2 worn iridium point.
Repair objective: MF (ball 0.8mm) nib with stub style point.
-all works went smoothly.
-a new type of point smoothing used. it used to take 15~30min to make perfect writing nib.
however, with upgraded type of smoothing technique, perfect griding is achieved in 1~3 minutes.
less iridium is worn down, as well as perfectly scratch free feel in all directions (all parts of the iridium point).
