All 13 types of urushi grip section development are completed.
As of now, I will end the urushi grip development.
grip section for Urushi is designed in such way,
urushi process is easier & urushi durability is better,
compared to a regular grip section design.
also, urushi grip section is thinner than a regular one.
because, urushi layers will make the part thicker.
even thread size is carefully considered for urushi process tolerance.
So far this year, I've completed...
11 types of ebonite feeders
dodecagon cigar symmetry (for urushi)
diamond dodecagon cigar symmetry (for urushi)
13 types of urushi compatible grip sections
from now on, i will reduce fountain pen research,
and focus more on production of non-urushi / urushi fountain pens.
thank you
