Knife or Death (officially Forged in Fire: Knife or Death) is an American competition series that airs on the History channel. It is a spin-off from the successful Forged in Fire television series.

The show is hosted by former NFL player and WCW/WWE professional wrestler Bill Goldberg, along with co-host Tu Lam, a former US Army Special Forces Soldier, martial artist and edged weapons expert. Two-time Forged in Fire champion Travis Wuertz assists as the show's blade inspection specialist.

On each episode, eight contestants compete through two rounds, using edged weapons that they have either forged themselves or had fabricated to their specifications. They must submit their weapons to a preliminary examination by Wuertz and can be immediately disqualified in case of a safety issue or failure. The contestant who finishes the second-round course in the shorter time advances to the season finale, with a $20,000 cash prize at stake.

Knife or Death premiered April 17, 2018 on History and is produced by Outpost Entertainment.
