The Tanto (protection sword) is the generic name for a sword of approximately 30.3cm length that serves as an every day tool, including as a dagger for children and women.
They were treated as some kind of charm (talisman) to drive away ill will and disasters.
Even today, among the ceremonies of the imperial household there is one called "Gift Sword Ceremony", in which when a child is born to the imperial family or to the family of one of the princes, a Tanto is gifted by the Emperor.
As a heirloom, used in prayers for the healthy growth of children and grandchildren and the peace of the house, and transmitted from generation to generation, the Tanto has been produced in Japan since ancient times.
In addition, there are questions and facts to verify prior to making a Tanto.
