SHOT Show
Yes, the steak featured on the show "Man v. Food" is called the Big 76er. It is a massive 76-ounce steak challenge served at the Big Texan Steak Ranch in Amarillo, Texas. Contestants have to finish the steak along with sides within a specific time limit to win a prize.
No. A butterfly knife is a knife in which the handles fold over the knife. It is one of the most impractical knife designs there is and is primarily used for entertainment and show reasons.

Steak,the type you eat.
Knife shows are most of the time being shown with most Gun shows. One can find some information about knife shows online at Gun Show, Great Southern Gun Show, Blade Show, Mi Gun Shows, Gibraltar Trade and Gun Show Trader.

I doubt they will let you bring a knife on the game show Survivor. It would be hard to pass through the airport with a knife, let alone bring it to a remote Survivor destination. Survivor has guidelines for what contestants can and cannot bring with them.
