Quick answer
Choose the GSH #6F for a close, even 3/16 inch (4.8mm) trim on coats you want kept short, and the GSH #4F for a medium 3/8 inch (9.6mm) finish that leaves more insulation and room for blending. Both are compatible with standard clipper models, so the decision comes down to the length you want on the dog, not the clipper.
What the cut lengths actually mean on a dog
The GSH #6F leaves hair at 3/16 inch (4.8mm), while the GSH #4F leaves it at 3/8 inch (9.6mm) — the #4F leaves roughly twice as much coat. On most breeds that difference shows up as a tighter, more uniform surface with the #6F and a softer, slightly fuller surface with the #4F. If you are aiming for a smooth, close finish on the body, the #6F gets you there in fewer passes. If you want a medium-length finish that still reads as a styled clip, the #4F is the more natural starting point.
Where each blade fits in a grooming routine
A practical way to split the work is to use the #4F for the main body run and the #6F for touch-ups, sanitary areas, or a shorter second pass when an owner asks for less coat. Because both blades are compatible with standard clipper models, you can swap them on the same clipper mid-groom without changing equipment. That makes them a sensible pair rather than an either/or purchase — the #4F sets the overall length and the #6F refines it.
Price and value trade-off
The GSH #6F is listed at USD 18.91 (catalog comparison price USD 31.00) and the GSH #4F at USD 21.60 (catalog comparison price USD 36.00). The #4F costs a few dollars more, but the gap is small enough that cut length — not price — should decide it. Buying both covers close and medium finishes and costs less than most single premium blades at their comparison prices.
What the catalog does not tell you
The supplied catalog facts list cut length, compatibility with standard clipper models, and intended use, but they do not specify which exact clipper models each blade fits or list available option types such as blade sizes in a set. If your clipper is an unusual model, confirm fit before ordering rather than assuming from the word "standard."
Trade-offs at a glance
- Length vs. insulation: The #6F leaves 3/16 inch (4.8mm) of coat; the #4F leaves 3/8 inch (9.6mm). Shorter coat is easier to keep clean and uniform but offers less protection from sun and cold. Pick the #6F for short, low-maintenance coats and the #4F for moderate length.
- Speed vs. forgiveness: The #6F removes more hair per pass, so a slip shows more clearly. The #4F leaves a cushion of coat that hides small uneven areas and blends better. Newer groomers often find the #4F more forgiving on the body.
- Cost vs. coverage: The #6F is USD 18.91 and the #4F is USD 21.60 at catalog prices. Buying both covers close and medium finishes for less than many single blades at their comparison prices. If you groom regularly, the pair is the practical buy.
