All American Sharpener Adapter Compatible with Honda Mower Blades [ONLY Works with Authentic

What It Is

This adapter lets you sharpen Honda lawn mower blades using an All American Sharpener. It’s designed for DIY blade maintenance, not for mounting or replacing blades.

Fitment & Compatibility

Before buying, confirm your All American Sharpener is the original model—this adapter only works with authentic All American sharpeners, not generic or clone units. It’s specifically made for Honda mower blades (most standard sizes used on HRX, HRR, and HRS series decks up to 21 inches). Measure your blade’s center hole diameter: Honda blades typically use a 15/16-inch or 1-inch hole. The adapter’s pin must match that hole size. Check your sharpener’s manual—if it lists “Honda adapter” as a separate accessory, this is it. Not for oval or non-standard Honda blade holes, or blades from other brands.

Key Things to Know

• Quality: The adapter is machined metal—durable, but some users report the pin can be slightly loose on older Honda blades. Check for wobble before sharpening.
• Installation: Easy—slides onto the sharpener’s arbor, then mounts the blade. No tools needed, but ensure the blade is centered and tight.
• Common gotcha: If your Honda blade has a different center hole shape (e.g., keyed or star), this adapter won’t fit. Only round holes work.
• Price point: $40 is steep for a simple adapter—only worth it if you already own an All American Sharpener and sharpen multiple Honda blades.

Should You Buy It

Buy this if you already have an authentic All American Sharpener, sharpen Honda blades regularly, and want a precise fit without jury-rigging. Skip it if you use a different sharpener brand, sharpen non-Honda blades, or only need occasional sharpening—a universal adapter or file will cost less.
