Medieval Information

Tean Zu is an ancient Chinese torture device originally designed for women, though it quickly appealed torturers for male victims. It's a relatively simple and yet painful torture, where a person's fingers were placed on a flat surface. Wooden sticks were placed between the fingers connected by strings. When a victim refused to talk or deliver information to the torturer, he would tighten the string a bit more causing the tables to crush the fingers.

This torture was sometimes used in the West, for it did not damage the skin nor kill the victim.
