What does "F" mean on a clipper blade?
F means Finish Cut: the teeth align for a smoother cut.
The confirmed #7F, #5F, #4F, and #3F entries use the Finish cut tooth type.
Skip tooth vs finish cut blades
Skip tooth blades open mats and support rough cutting; do not use them for direct skin clipping.
Finish-cut blades use aligned teeth for a smoother result.
Why blade numbers seem backwards
The convention comes from early barber clipper numbering: higher numbers leave less hair.
