By far the Zebra G is the best for flexibility of producing very fine and thick
lines. Then followed by Nikko G (stiffer nib, produces fine lines but not as
flexible as the Zebra), then the Tachkawa G (falls between the Nikko G and Zebra
G) for pointed pen calligraphy work. Calligraphers, penmen and Master Penmen
alike recommend this nib and call it a "workhorse" of a nib. They suggest
initial treatment to the nib (to remove the protective sheen on the nib) by
either running the bottom of the nib under a lit match for 3 seconds; or use
liquid gum arabic to wipe the nib or rub it with some toothpaste and rinse. Any
of these techniques will work before dipping the nib into ink. Hope this helps!
