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

What It Is

The Sharpener Model 5005 is a manual jig that sharpens standard lawn mower blades (straight and curved) at an adjustable angle from 15° to 45°. It’s designed for residential mowers with blade lengths up to 22 inches, not for commercial zero-turn or mulching blades with deep curves.

Fitment & Compatibility

• Blade type: Works with straight and standard curved blades (up to ~2” wide). Not for blades with severe bends, notches, or hardened coatings.
• Angle range: 15°–45°; most residential blades use 30°–35°. Measure your blade’s bevel with a protractor or angle gauge before setting.
• Blade length: Fits blades up to 22”. Longer blades (e.g., 24”+) won’t clamp securely.
• Mounting: Requires a stable workbench or vise. No drill or power tool needed—you clamp the blade in the jig and file by hand.
• OEM vs aftermarket: Works with any standard blade that fits the size limits. No brand-specific adapters.

Key Things to Know

• Manual effort: You sharpen by hand with a file (not included). This gives control but takes 5–10 minutes per blade. Not for high-volume sharpening.
• Angle setting: The adjustment is a thumb screw—mark your setting with a pen or tape for repeatability. It can slip if not tightened fully.
• Clamp strength: The clamp holds blades up to ¼” thick. Thicker or warped blades may wobble.
• No guide for balance: After sharpening, you must check blade balance separately (use a blade balancer or nail). An unbalanced blade vibrates and risks spindle damage.

Should You Buy It

Yes if you own one or two push mowers and want a precise, repeatable edge without buying a bench grinder. Skip it if you sharpen multiple blades weekly (too slow) or need to sharpen mulching or notched blades—this jig won’t hold them securely. For $38, it’s a solid entry-level sharpener for DIY homeowners.
