Model 5005 Lawn Mower Blade Sharpener Kit 15°-45°Adjustable for Straight and Standard Lawnmower Blades

What It Is

The Model 5005 Lawn Mower Blade Sharpener Kit is a handheld sharpening guide that holds your blade at a fixed angle (15° to 45°) while you file, grind, or sand the cutting edge. It’s designed for home mechanics sharpening straight or standard curved lawn mower blades—not for mulching or serrated blades.

Fitment & Compatibility

• Blade type: Works with straight and standard curved blades only. Not compatible with serrated, notched, or mulching blades.
• Blade thickness: Fits blades up to 3/8” thick. Measure your blade’s thickness before buying.
• Angle range: Adjustable from 15° to 45° in 5° increments. Most walk-behind mower blades use 30°–35°; check your blade’s factory bevel.
• Brand/model: Universal—no specific mower brand required. Works with any blade that meets the thickness and shape limits.
• What to check: Blade thickness, blade type (straight/curved vs. serrated), and factory bevel angle. If your blade is thicker than 3/8” or has a serrated edge, this kit won’t fit.

Key Things to Know

• Quality: Solid metal construction with a clear angle lock. Holds blade securely; no wobble during filing.
• Installation difficulty: Very easy—clamp blade in a vise, set angle, and file. No power tools needed.
• Gotcha: The kit includes a file guide but no file or sharpening stone. You’ll need to buy a 10” flat file separately.
• Gotcha: The clamp can slip on very thin blades (under 1/8”) if not tightened fully. Double-check the thumbscrew.

Should You Buy It

Buy this if you sharpen 2–4 mower blades per season and want consistent, repeatable bevels without buying a bench grinder. Skip it if you only sharpen once a year (a basic hand file will do) or if you need to sharpen mulching/serrated blades.
