Buster Warenski (June 5, 1942–July 31, 2005) was a custom knifemaker from Kimberly, Nevada who made "Art Knives" utilizing gold and other precious metals. Warenski is best known for making a reproduction of King Tut's dagger with a cast blade; over 32 ounces of gold were used in the construction of the dagger, making it one of the most valuable knives made in recent years.

Warenski began making knives as a hobby in 1966 after seeing a picture of a knife made by Gil Hibben. Warenski made his first knife from a file and took it to show Hibben; after seeing Hibben's finished knives, he toured Hibben's shop and learned some basic techniques from him. In June of 1972 he was hired by Harvey Draper to grind blades and assist him at Draper Knives, but the operation went bankrupt by December of the same year. Warenski became a full time knifemaker in 1975. He was a president of the Knifemakers' Guild for 2 terms and a Blade Magazine member of the Cutlery Hall of Fame.
