Sharpening small pruning shears means cleaning the blades first, then filing only the beveled cutting edge at its original angle.
For the full breakdown, see our best Small Pruning Shears guide.
Dull blades crush stems instead of cutting them, which invites disease into your plants.
What You’ll Need Before You Start
Gather the right tools before you begin. You don’t need anything fancy or expensive to get a razor edge back on small pruning shears.
- Cleaning supplies: soap, water, a cloth, and a scouring pad or fine steel wool.
- Sharpening tool: a flat file, a whetstone (around 220 grit for coarse work, 1000 grit for finishing), or a dedicated blade sharpener.
- Protection: work gloves and eye protection. File away from your body, never toward it.
- Lubricant: a light machine oil or 3-in-1 oil for the final step.
Step-By-Step: Sharpening Small Pruning Shears
The process follows a clean, inspect, sharpen, and finish sequence.
Step 1: Clean the Blades Thoroughly
Remove sap, dirt, rust, and plant debris before you touch a file to the metal. Wash the blades with soapy water and scrub with a scouring pad or steel wool. Dry completely.
Step 2: Find and Match the Bevel
Look at the cutting blade’s edge. Bypass and most anvil pruners have one angled, beveled edge on the cutting blade and one flat side on the mating blade. You sharpen only the beveled side—never the flat side, which would ruin the blade’s geometry.
