Re: griptape on bokken
Seiser Sensei is correct about the laws of California. A simple bokken or jo with the handle clearly defined with tape (or something else) becomes a billy club under California law and mere possession is a felony. Carrying a loaded and concealed handgun is only a misdemeanor - go figure. I doubt that any aikido student would run into a problem with the police here on the Left Coast, but it could happen I suppose.
