On Blaze TV there is a series of programs called Forged In Fire
In each program 4 blacksmiths come into the studio "smithy" and are given 3 hours to design and forge a knife blade using a variety of secondhand materials and a variety of different techniques. The quality of the raw blades are then judged and one person is eliminated.
The 3 remaining blacksmiths are then given another 2/3 hours to refine the blade and attach a handle. This time the blades are put through a series of slashing, cutting, sharpness, tempering and strength tests with another person being eliminated.
If watching the programs in the evenings the expert judges are shown performing the tests including the martial arts expert effectively disemboweling and spearing a human dummy. During the daytime showing of the same programs all the tests showing the effective techniques of using a bladed weapon are edited out presumably in order not to give school kids any new ideas.
Hint: if your kids want to learn how to kill someone with a knife just record the evening edition!
The type of test that may be left in is firing a bullet at a blade edge and the blade splitting the bullet, usually without any edge damage.
In the final part of the program the two remaining contestants are asked to manufacture a copy of a named historic bladed weapon (knife, spear, sword etc.) and send back to their own forges where they are given a week to complete the challenge. The final product is put through a series of performance testing where any usage techniques are edited out of the daytime showing. The winner of each program gets $10,000.
