Tenugui
Tenugui are hand cloths used by Japanese people. Most of them carry a tenugui of some form with them every day, Public toilets do not have hand towels so they use their own towel in their pocket to dry their hands. They are used by Martial Artists as a sweat cloth, kendo people wrap them around their head prior to wearing the helmet. Takagi Yoshin Ryu says you should carry one with you at all times and even has forms for using it
