What does F mean on clipper blades?

Professional pet stylists selecting A5 detachable clippers frequently ask: what does fs mean on clipper blades or what does the “F” stamp indicate? Master blade sharpeners and clipper engineers explain: the letter “F” or “FS” stands for “Finish / Full Tooth,” indicating that all cutting teeth on the blade comb are uniformly spaced and equal in length to produce a plush, velvet-smooth finish cut; in contrast to “Skip Tooth” (ST) blades which have alternating short/long teeth designed to feed through heavy matted coats before the final “F/FS” blade pass.

Blade Mechanics Explained: What Does F or What Does FS Mean on Clipper Blades?

Understanding clipper blade anatomy prevents track marks and skin nicks. When asking what does fs mean on clipper blades (e.g. #7F, #5F, #4F vs #7 Skip Tooth), review this technical engineering comparison:

Blade Designation / SuffixComb Tooth GeometryPrimary Grooming PurposeSafety & Finish Quality Rating
“F” or “FS” (Full / Finish Blade)Every tooth is identical in length and tightly spacedSmooth, velvety final body styling after bath & force blowoutSAFEST & SMOOTHEST; skin folds cannot easily enter teeth
“Skip Tooth” / “ST” (No “F” Stamp)Alternating wide gaps between tall and short teethRough pre-bath clip; feeds dense matted fur into cutting railHIGH CAUTION; loose dog skin can snag in wide tooth gaps
Wide “F” Blades (e.g. 7FW, 5FW, 4FW)35% wider cutting path with full-tooth geometrySpeeds up body clipping on large Doodles, Goldens, and NewfoundlandsCuts salon grooming time by 30% without leaving blade lines
CeramicEdge / Titanium Coated “F”Full tooth geometry with zirconia ceramic cutting insertRuns up to 75% cooler than standard carbon steel bladesPrevents thermal clipper burn during extended full-body clips

Top 3 Clipper Blade Maintenance Best Practices

  1. Oil Every 15–20 Minutes: Place 3 drops of clipper oil across the teeth and 1 drop on the rear glide rail while running to prevent blade overheating.
  2. Use Blade Wash (Not Water): Submerge running blade tips in professional blade wash for 5 seconds to flush out trapped pet hair and dander.
  3. Check Blade Drive Snugness: Replace your clipper’s plastic blade drive lever every 3 to 6 months to prevent blade rattling and uneven cutting lines.

Frequently Asked Questions (FAQ)

What is the difference between a #7 and a #7F blade?

A #7 is a skip-tooth blade used for rough matted coat clearance, whereas a #7F has full, uniform teeth designed for a smooth final finish.

Can an “F” blade cut through thick mats?

No. Dense mats will push an “F” blade away from the skin; use a skip tooth blade or #10 blade to slide underneath felted mats safely.

Why do clipper blades get hot during grooming?

Metal-on-metal friction at 3,000+ strokes per minute generates heat; use ceramic cutters, cool care spray, and blade rotation every 10 minutes.
