Introduction
The Corona RS 7245 Razor Tooth Folding Saw is a compact, high-performance pruning tool designed for efficient cutting of small to medium branches. Its 7-inch curved, high-carbon steel blade ensures clean, aggressive cuts with minimal effort, maintaining sharpness for extended use. This lightweight saw is ideal for various outdoor tasks including tree trimming, pruning, landscaping, camping, backpacking, trail maintenance, and general yard work. The curved blade design maximizes tooth contact for improved cutting speed and control, while the folding lock-back mechanism ensures safe operation and secure storage.
Safety Information
- Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when operating the saw.
- Ensure the blade is fully locked in the open position before use.
- Keep hands and other body parts clear of the blade during operation.
- Exercise caution when folding and unfolding the saw to prevent accidental cuts.
- Store the saw in its folded and locked position when not in use, out of reach of children.
- Do not attempt to cut branches thicker than the recommended capacity (up to 3 inches for this model).
- Avoid cutting into metal or other hard materials that could damage the blade.
- Clean the blade after each use to prevent sap and debris buildup, which can affect performance and lead to corrosion.
Setup
- Unfolding the Saw: Locate the locking mechanism near the pivot point of the blade. Press the button or lever to release the blade. Carefully swing the blade out until it fully extends and locks into place. Ensure the blade is securely locked before proceeding.
- Inspecting the Blade: Before each use, inspect the blade for any damage, dullness, or excessive rust. A sharp, clean blade ensures optimal cutting performance and safety.
- Handle Grip: The ergonomic handle is designed for a comfortable and secure grip. Ensure your hand is positioned firmly on the handle to maintain control during cutting.

Operating Instructions
- Positioning: Identify the branch to be cut. Position yourself securely, ensuring a stable footing and clear space around the cutting area. Avoid overreaching.
- Starting the Cut: Place the blade on the branch at the desired cutting point. Apply light pressure and initiate the cut with a pull stroke. The razor teeth are designed for efficient cutting on the pull stroke.
- Cutting Technique: Use long, steady pull strokes, allowing the saw's teeth to do the work. Avoid pushing the saw too hard, as this can cause the blade to bind or bend. Maintain a consistent rhythm.
- Completing the Cut: As the cut deepens, support the branch to prevent it from tearing or falling unexpectedly. Once the cut is complete, carefully remove the saw.
- Folding the Saw: After use, ensure the blade is clean and free of debris. Press the locking mechanism to release the blade and carefully fold it back into the handle until it clicks securely into the closed position.

Maintenance
- Cleaning: After each use, clean the blade with a damp cloth to remove sap, resin, and debris. For stubborn residue, use a specialized blade cleaner or a mild solvent. Dry the blade thoroughly to prevent rust.
- Lubrication: Apply a light coat of rust-preventative oil to the blade and pivot point periodically, especially before long-term storage.
- Blade Sharpening: The razor teeth are impulse-hardened for long-lasting sharpness. While designed for durability, if the blade becomes dull or damaged, replacement blades are available. Attempting to sharpen these specialized teeth yourself is not recommended and may void the warranty.
- Storage: Always store the saw in its folded and locked position in a dry environment to prevent corrosion and accidental injury.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Blade binds during cutting | Applying too much pressure; cutting green wood; dull blade. | Use lighter, longer pull strokes. Ensure the blade is clean and sharp. Consider a replacement blade if dull. |
| Saw feels wobbly or loose | Loose pivot bolt. | Check the pivot bolt. If it's missing or loose, replace or tighten it. Applying threadlocker (Loctite) is recommended to prevent loosening. |
| Blade is corroded or rusty | Improper cleaning or storage; exposure to moisture. | Clean the blade thoroughly and apply rust-preventative oil. Store in a dry place. |
