How do I clean and sharpen pruning tools?
Clean after every use, disinfect between diseased plants, sharpen along the bevel and oil the pivot.
Start here
Wipe the blades clean after every session, disinfect between diseased plants, sharpen when cuts start to tear, and oil the pivot. That’s the whole routine.
Cleaning
Sap and grime build up fast. Scrub with warm soapy water and a stiff brush, then dry fully. If you’ve cut diseased wood, wipe the blades with rubbing alcohol or a household disinfectant before moving to the next plant.
Sharpening
- Use a fine sharpening stone or a diamond file.
- Follow the existing bevel angle on the cutting blade only.
- Work in smooth strokes from the pivot toward the tip.
- Remove the small burr on the flat side with one light pass.
Oil and storage
A drop of light oil on the pivot and a thin film on the blades stops rust. Store tools dry and off the ground. Loose pivot bolts make sloppy cuts, so tighten them now and then.
Safety
Wear gloves when sharpening. Keep the blade closed when not in use.
