Which blade yields a 9 mm cut?

Which blade yields a 9 mm cut?

• A. #10
• B. #4F
• C. #7F
• D. #3F

Answer: (B)

Understanding blade length mapping. In dog grooming, the blade size tells you how long the coat will be left after trimming; the label on the blade corresponds to a specific cut length, with the “F” variation indicating a fine-tooth version of that length. The blade labeled 4F leaves about 9 mm of hair (roughly 3/8 inch), which is why it’s the right choice for a 9 mm result. The other blades in the list are designed to leave different lengths, so they won’t produce an exactly 9 mm cut. If you’re ever unsure, check your clipper brand’s blade length chart for the precise measurements.
