Use a comb for laying your hair flat and buzzing it against the grain. Use a closed lever without a guard or a number one guard depending upon the type of shave of the first one. A bald trimmer will help you to shave as closely as possible.
Trim the portion around the ears without using a guard to a width of around 1 inch.This will give you a foundation for the burst fade to go down to a lower length. Use the number 4 guard for having the sides cut to the desired length.You can also use a scissor as long as you can handle it in order to cut the hair to the desired length. Set the clipper with number 3 guard to keep the hair on the top to the desired length.
