While neighbors obsess over fertilizers and watering schedules, the real secret to a lush lawn lives in your garage. A sharp mower blade makes all the difference between a healthy carpet of green and a ragged, disease-prone yard. My grandfather’s Depression-era sharpening trick requires just four common household items and delivers professional results.
After removing the blade (always with the mower off and spark plug disconnected), spray WD-40 on sandpaper secured to a wooden block. A few careful strokes at the proper angle restores the blade’s edge better than most store-bought sharpeners. The technique’s brilliance lies in its simplicity – no special skills required, just basic safety precautions.
The payoff? Grass that heals faster, grows thicker, and withstands drought better. Your mower will thank you too, running smoother and lasting longer between repairs. This forgotten wisdom from generations past could save you hundreds in professional sharpening costs while giving you the healthiest lawn on the block.
