Quick answer
Choose the Andis 5FW blade for a smoother finish on fine or medium coats, or the 4FW blade for faster cutting on thick, coarse coats. Both fit all professional Andis detachable blade clippers.
Why tooth count matters for your dog's coat
The number of teeth on a clipper blade directly affects how the blade handles different coat types. More teeth (like the 5FW's 31) create a finer, closer cut with less vibration, ideal for sensitive skin or thin fur. Fewer teeth (like the 4FW) leave more space between each tooth, allowing the blade to grab and cut through thick, matted hair more aggressively.
Both blades are detachable, making them easy to swap between clippers without tools. They also share the same compatibility with all professional Andis detachable blade clippers, so your decision comes down to coat type and finish preference.
Trade-offs between the 5FW and 4FW
The 5FW blade's 31-tooth design delivers a noticeably smoother finish, which reduces the chance of irritation on dogs with sensitive skin. However, the extra teeth mean it can clog more quickly on heavy, dense coats, requiring more frequent cleaning.
The 4FW blade, with its wider tooth spacing, powers through thick fur faster and stays cleaner longer during heavy use. The trade-off is a slightly rougher finish that may not be as comfortable for dogs with fine hair or sensitive skin.
How to choose between the Andis 5FW and 4FW blades
- Coat thickness: For thick, coarse coats, the 4FW's wider tooth spacing cuts faster and resists clogging. For fine or medium coats, the 5FW's 31 teeth give a smoother, more comfortable finish.
- Finish quality: If you prioritize a polished, irritation-free finish (e.g., for show dogs or pets with sensitive skin), choose the 5FW. If speed and power are more important, the 4FW is the better option.
- Maintenance frequency: The 5FW requires more frequent cleaning during heavy use because its tighter teeth trap hair faster. The 4FW stays cleaner longer between brush-outs. Plan to stop and clean the 5FW blade more often when working on thick coats.
