The Andis UltraEdge Size 4F is a detachable finish-cut blade for leaving a fuller coat with a consistent appearance. Andis identifies manufacturer item 64123 as size 4FC, with a nominal cutting length of 3/8 inch (9.5 mm). It is a useful finishing option for body grooming when the planned trim should retain that amount of hair.

The finish-cut tooth design supports even clipping and blending across the coat. UltraEdge blades use a hardening process intended to help preserve the cutting edge, with a chrome finish that helps resist corrosion. Choose the finish-cut version when the goal is a smooth overall result; the blade size and tooth pattern together identify the intended cut.

Brush out hair and debris, oil as directed in the clipper manual, and follow its blade-removal and refitting instructions.
