Well, since Isshin says that the charm was made especially for Kon, I guess Masaki didn't make it after all. However, if you read/listen to what Isshin actually says to Kon, Isshin never says that HE made it himself. I've listed quotes from the manga, and anime, below.

Manga:"Hey! Catch, Kon. This charm was meant for you to begin with."

Anime:"Here, Kon, hold on to this. It's a charm that was created just for you; I meant to give it to you."

I agree with you that Isshin never ceased to be a Shinigami, otherwise he wouldn't have been able to help Masaki. Isshin's Shinigami/Human nature was essential to balance out Masaki's Quincy/Hollow nature. My point is that since Kisuke clearly stated that Isshin would never have access to his Shinigami powers, while inside the shell, Isshin therefore couldn't have made the charm. That's why I mentioned Kisuke, and Ryuken, as possible creators.
