A sharp pair of pruning shears makes every cut cleaner and every gardening session easier. Yet many gardeners use dull tools for years without realizing the difference sharpening makes.
Why Sharpness Matters
Dull blades crush and tear plant tissue rather than cutting cleanly. This creates ragged wounds that heal slowly and invite disease. Sharp tools reduce plant stress and your own hand fatigue.
How Often to Sharpen
Home gardeners should sharpen pruning shears at least once per season—more often with heavy use. If you notice the blades tearing rather than slicing, it’s time for sharpening.
Simple Sharpening Steps
Clean the blade with rubbing alcohol first. Use a fine-grit whetstone or diamond file. Maintain the existing bevel angle—usually about 20 degrees. Stroke in one direction only, from base to tip. Ten to fifteen strokes typically restores a good edge.
Don’t Forget Maintenance
Wipe blades with an oily rag after each use to prevent rust. Tighten the pivot bolt if blades become loose. Store tools in a dry location over winter.
When to Replace
If blades are badly nicked, bent, or pitted with rust, replacement makes more sense than continued sharpening. Quality shears last many years with proper care.
