He was born in Los Angeles, California. In May, 2006, he was ordained as a minister by the Sinagogue of Satan through the Universal Life Church. He received his license to perform marriages in the State of California as a "Cannabis Sacrament" Minister and founded the TSC Ministry.
A former Democratic-Republican, Knife is now a pro-marijuana and hemp activist from the Cannabis Assembly. He has written over a dozen books and only 5 were published, one being the aforementioned Yes I Cannabis. There has also been a documentary made about his life in the indie music scene. He believes that the hemp plant (as well as inmates convicted of marijuana charges) should be decriminalized because it has been shown to be less harmful then any known drug, could be a renewable source of fuel, food, and medicine, and can be grown in virtually any part of the world, and that the U.S. government deliberately hides the proof of this. He has devoted his life to the support of cannabis, hemp and marijuana.
"Knife" Sotelo also gave his name to a specific technique in cannabis consumption.
In 2004, he joined the THC Ministry, a religion that considers cannabis to be a sacrament.
Sotelo is running for a congressional seat on the United States House of Representatives in 2016 as a Grassroots Party candidate.
