Question: what is a 1 buzz cut?
Answer: Step #1: Choose a Length The standard cut you should go with is a 3-2-1 buzzcut, which has a No. 3 guard on top, No. 2 on the sides, and No. 1 around the edges. This will leave the hair about 3/8 inch long on top, tapering down to 1/2 inch on the sides and back and then finishing tighter at the hairline.
