With regular use secateurs can become gummed up with sticky plant sap and debris, which needs to be removed for the blades to cut cleanly so that the plants being pruned are not left with ragged cuts that can lead to infection. If soil and grime get into the moving parts, they will cause excessive wear and allow rust to develop.
Precision-ground surfaces
Bypass cutting-action blades should be wiped after each use with an oiled cloth but, over time, the secateurs will tend to lose their edge and need sharpening. These are good-quality blades, precision ground by machine to form two edges that pass one another closely to cut using a scissor action.
For this reason, these two surfaces should be cleaned using an abrasive that does not damage the metal, and never cleaned with a file. If the precision-ground surfaces are damaged, this will impair the cutting action.
