Famore Cutlery 400RT Rotary Blade Handle

What It Is

The Famore Cutlery 400RT is a rotary blade handle designed for manually sharpening lawn mower blades. It holds the blade securely for hand filing, making it ideal for DIY maintenance on walk-behind mowers, riding mowers, and zero-turn mowers.

Fitment & Compatibility

Before buying, confirm your blade’s center hole diameter—the 400RT fits blades with a 1-inch (25.4mm) center hole, common on most residential mowers. It does not fit blades with larger or non-standard holes (e.g., 7/8-inch or 1-1/4-inch). The handle works with any brand or model (Toro, Honda, Craftsman, John Deere, etc.) as long as the blade has a 1-inch hole. No deck size restrictions apply, but the handle is not for mulching or gator blades with irregular shapes. It’s an aftermarket accessory; no OEM compatibility issues.

Key Things to Know

• Quality: The handle is made from heavy-duty steel with a rubberized grip, providing a secure hold and good leverage. It’s durable but not indestructible—avoid overtightening the clamp.
• Installation difficulty: Very easy. Slide the blade’s center hole over the handle’s shaft, tighten the knob, and you’re ready to file. No tools needed.
• Common gotchas: The handle doesn’t include a file—buy a flat file separately. It’s not for balancing blades; use a separate balancer. The clamp may slip on very narrow or thin blades (under 2.5 inches wide). Check blade thickness: works best with 0.125-0.200-inch blades.
• Storage: The handle is compact but not foldable; store in a toolbox or hang on a pegboard.

Should You Buy It

Buy this if you sharpen your own mower blades at least twice a season and want a safer, more comfortable alternative to holding a blade barehanded or with a vice. It’s perfect for DIYers with standard 1-inch hole blades who value simplicity over a full sharpening kit. Skip it if you use non-standard blades or prefer a bench grinder.
