Weird Patent of the Day
Tooth cleaning and gum massaging instrumentality
A fingercot useful in cleaning teeth and massaging gums. Earlier finger cots often confined their pointed protuberances to one side, which made it necessary to shift the cot from one hand to the other; this invention is directed to that problem.
