Authentic All American Sharpener Model 5005 Gen 2 - Invented and Made in the USA (15°-45° Adjustable Lawn Mower Blade Sharpener for Right and Left Hand Blades)…

What It Is

The Authentic All American Sharpener Model 5005 Gen 2 is a manual bench-mounted sharpener for lawn mower blades, designed to handle both right- and left-hand blades with an adjustable angle range of 15° to 45°. It’s for residential or light commercial use—ideal for homeowners or small shops who sharpen multiple blades per season.

Fitment & Compatibility

• Blade type: Works with any standard walk-behind mower blade (up to ~24 inches long) and most riding mower blades. Not for reel mowers or zero-turn blades with non-standard mounting holes.
• Angle range: Adjustable from 15° to 45°, covering nearly all OEM blade angles. Check your blade’s factory bevel (typically 30°–35° for push mowers).
• Blade orientation: Accepts both right-hand and left-hand blades without flipping the sharpener.
• Mounting: Requires a sturdy workbench or table; clamps or bolts down via two predrilled holes (4-inch centers). No adapter needed for most blade types.
• What to check before buying: Measure your blade’s length and center hole diameter (common sizes: 1/2”, 5/8”, 1”). The sharpener’s guide pins fit standard 1/2” and 5/8” holes; larger holes may need a bushing (not included). Verify your blade isn’t excessively worn (more than 1/8” off) or bent.

Key Things to Know

• Quality: Cast-iron construction with hardened steel guides—built to last decades. Made in the USA, no plastic parts.
• Installation difficulty: Easy to mount (drill two holes or use clamps), but sharpening requires manual effort and a steady hand. Not for beginners who want a power sharpener.
• Common gotchas: The sharpener uses a standard 1/2” arbor (included) for a bench grinder or drill—you supply the grinding wheel (recommend 6” x 1/2” fine grit). Over-tightening the blade clamp can warp thin blades. Always sharpen in the same direction (from center to tip) to avoid overheating.
• Maintenance: Clean debris from guide slots after each use; occasional oil on pivot points.

Should You Buy It

Yes if you sharpen 5+ blades per season, want a precise, adjustable edge, and prefer a manual tool over a powered grinder. Skip it if you only sharpen one blade a year or need a quick, no-setup solution. At $200, it’s a buy-it-for-life investment for dedicated DIYers or small repair shops.
