As you might have guessed, the Heretic’s Fork was invented during the Spanish Inquisition. The fork would have two pointed edges on each end and would be attached to a leather strap that would go around the victim’s neck. One pointed end went just underneath the victim’s chin while the other would be pointed down into the person’s sternum. Even the slightest movement of the jaw would result in unbelievable anguish. If used, it would almost always be a prelude to being burned at the stake.
