Corona Pruner Blade Replacement: Which Blade Fits Your Model?

Why Replace Your Corona Saw Blade?
Corona pruning saws are built tough, but their blades don't last forever. Razor tooth blades are hardened for sharpness and longevity, but they're not designed to be resharpened — when the teeth dull, the right move is a blade swap, not a new saw. A fresh blade restores full cutting performance in minutes and costs a fraction of a replacement saw.
This guide covers which replacement blade fits each Corona saw model, plus a step-by-step walkthrough of the replacement process.

When to Replace Your Corona Saw Blade
Corona's razor tooth blades are triple-ground and hardened — they stay sharp longer than standard blades, but they're not resharpenable. Replace the blade when you notice:
- Increased cutting effort — you're pushing harder to make the same cuts
- Tearing rather than slicing — the blade drags and catches instead of cutting cleanly
- Visible tooth damage — bent, chipped, or missing teeth
- Rust or pitting on the blade surface that affects the cut
For most home gardeners, a blade lasts 1–3 seasons depending on use. Professional users (arborists, landscapers, orchardists) may replace blades annually or more frequently.
How to Replace a Corona Folding Saw Blade
Replacing a Corona folding saw blade is a straightforward process that takes about 5 minutes. You'll need a screwdriver or hex key (size varies by model — check your saw's hardware).
Step 1: Open and lock the saw.
Open the blade to the fully extended, locked position. Never attempt blade removal with the saw folded — the spring tension makes it unsafe.
Step 2: Locate the anchor screw.
The blade is secured to the handle by a pivot bolt and, on most models, an anchor screw near the spine of the blade. If your saw uses an anchor screw, you may need a Corona Replacement Saw Blade Anchor Screw 6801-36 if the original is worn.
Step 3: Remove the fasteners.
Unscrew the anchor screw first (if present), then loosen the pivot bolt. Keep all hardware in a small container — these are easy to lose.
Step 4: Slide out the old blade.
With the fasteners removed, the blade slides out of the handle channel. Note the orientation before removing it.
Step 5: Insert the new blade.
Slide the new blade into the handle channel in the same orientation as the old one. Align the mounting holes with the pivot bolt hole.
Step 6: Reinstall the fasteners.
Thread the pivot bolt back in and tighten firmly — but don't overtighten, as this can bind the folding mechanism. Reinstall the anchor screw if applicable. On fixed-blade models, you may also need a Corona Replacement Mounting Ferrule - Saw Blade 6881-44 if the ferrule shows wear.
Step 7: Test the action.
Open and close the saw several times to confirm smooth operation. The blade should lock firmly in the open position with no wobble.

Extend the Life of Your New Blade
- Wipe the blade after each use — sap and resin accelerate corrosion and dull teeth faster
- Store folded — keeping the blade protected when not in use prevents accidental tooth damage
- Avoid cutting soil or wire — even brief contact with soil or metal dulls razor teeth immediately
- Oil occasionally — a light wipe of camellia or machine oil prevents rust during storage
