Platinum nib compatible ebonite feed has been developed
this requires specially designed grip section
overall feed design is similar to Bock compatible ebonite feed except:
1) nib groove
2) tail size
3) frontal slant angle
after making certain amount of these,
i will move onto making ebonite grip section for urushi coating
after that i will make some ebonite grip section for regular models
these will be compatible with previously made barrel and cap,
and will fit the 5th gen ebonite feed
