Marvin Aborca Sotelo who usually goes by M.A. Sotelo or "Knife" Sotelo is an American gangster as well as a rapper, producer, occultist, writer, and record executive from East Los Angeles, California.

Knife is best known as a gangster as well as a rapper, producer, occultist, writer, and conspiracy theorist. He is also the only rapper of Filipino and Spaniard descent to be labeled under Chicano rap since Chicano rap is mainly rappers of Mexican descent. Although his style is generally considered Chicano rap, his ambiguous ethnicity may have caused him to declaim the genre, preferring to style himself as a "Maravilla rapper" or "Greenlight rapper", he coins his music Chavacano rap since Filipino rap is heterogeneous, encompassing rap in languages such as Tagalog, Chavacano, Spanish and Ilocano, as well as English. Knife is considered by many to be a driving force in bringing back the Gangsta rap scene and was popularly thought to be the impetus behind the development of Chavacano gangsta rap in the United States.
