How bypass pruners work
Bypass pruners cut with the blade passing by the counter surface, similar to scissors. This produces clean cuts – but only if the beveled side is sharpened correctly.
How to sharpen bypass pruners
- Open the pruners as wide as possible to access the blade
- Place the diamond sharpener against the beveled edge
- Follow the existing angle and file along the edge
- Continue until the edge becomes smooth and even
- Lightly remove the burr from the inside
Important: only sharpen the beveled side
Do not sharpen the flat side of the blade or the counter surface. This will create a gap and reduce cutting performance.
Why removing the burr matters
A remaining burr will cause the edge to lose sharpness quickly. Always remove it with light strokes on both sides.
Result
- Less effort when cutting
- Cleaner cuts
- Longer tool life
Using a diamond sharpener?
A fine diamond sharpener restores the edge in just a few strokes.
