Great comments, thanks.

Janet some people recommend hatpins for women to strike against straying hands on crowded trains. It's a problem on some train lines in Japan.

Diana the scream is a good technique! I don't recommend ripping the mouth though except as a last resport!

Ah Henry, yes that is wise advice.

Thanks Graham. I didn't think of crutches!

Thanks Oisin. I didn't know that. I've never seen umbrella techniques demonstrated. By the way I have an iron shakuhachi which could double as an effective weapon.

Thanks for those Carina. Some hotel keyrings are about the same size as a kubotan too.
