One of the most distinguishing features of the Fuji Feather Professional is the Ishiwata fork. They are so unique there is no mistaking the fork if you happen to discover one. However, most the forks I have been able to acquire are too worn at the dropouts and the “Ishiwata” text engraving is gone.

It seems many people replaced the original forks with something after-market. I’m not sure if this is due to breakage or the unusual geometry. Both the frame and fork tubing of the Fuji Feather Professional were stamped and manufactured by Ishiwata Seisakusho Co. LTD. in Japan.
