Most barbers are running detachable blades every day, but a lot of y’all don’t really understand what each number is doing—so the results get inconsistent. In this video, I break down detachable blade numbers from 00000 all the way up through 3 and the 1 1/2, and I explain what I’m actually using each one for behind the chair. This isn’t theory—this is about controlling bulk, blending clean, debulking faster, and staying precise without guessing. I talk through real application: when I’d grab a 00000 versus a 0A, why a 1A can make more sense than a 1 depending on the cut, and how a 1 1/2 sets you up for cleaner transitions so you’re not fighting your fade. Detachable clippers are powerful, but power without knowledge creates inconsistency. If you want sharper fades, cleaner debulking, and more confidence at your station, mastering blade selection is the foundation—before you go buy something new, watch a concise review and learn what you already have.
