Keeping your pruners sharp and well-maintained is crucial for healthy and efficient pruning. Sharp pruner blades ensure clean cuts, which help prevent damage to your plants and promote faster healing. In this guide, we’ll walk you through the entire process of sharpening pruners, from cleaning the blades to proper sharpening techniques and post-sharpening care.
Let’s dive into the steps to keep your pruners in peak condition for every job.
Step 1: Cleaning Your Pruners Before Sharpening
Before you even think about sharpening, it’s essential to start with clean blades. Sap, dirt, and rust buildup on your pruner blades can dull them over time and make sharpening difficult. A clean blade will ensure you sharpen evenly and effectively.
How to Clean Pruner Blades
- For heavy sap and dirt deposits: Use a high-quality blade cleaner. FELCO Tool Spray is an excellent option that quickly removes stubborn grime.
- For light rust: If your pruners have minor rust spots, a wire brush or fine sandpaper works well to buff them away. Be gentle to avoid scratching the metal.
- Dry thoroughly: Once your pruners are free from debris and rust, dry them completely to avoid any moisture buildup, which could lead to more rust.
Now that your blades are clean, you’re ready to sharpen.
Step 2: Sharpening Your Pruner Blades
Sharpening pruners is a simple process, but it’s important to use the right tools and technique to achieve a sharp, long-lasting edge. You can use a whetstone or carbide sharpener to get the job done.
Sharpening Technique
- Choose your sharpener: A whetstone or carbide sharpener will work well, but make sure it’s suitable for the type of blade you’re sharpening. Both options allow for precise control over the sharpening process.
- Angle the blade: The key to sharpening pruners is maintaining the correct bevel angle. Most pruners, like the trusted Felco F2 Pruners, have a bevel angle of 23º. If you're using a different pruner model, check the manufacturer’s specifications for the bevel angle.
- Smooth strokes: Starting from the center bolt and moving toward the blade's edge, make five to ten smooth, even strokes with the sharpener. Maintain a consistent angle as you move to avoid creating an uneven edge.
- Remove burrs: After sharpening the primary blade, turn it over and use a single, flat stroke to remove any burrs from the back of the blade. Be sure to check the counter blade as well and remove any burrs there.
Quick Tip: Check Blade Alignment
When sharpening your pruners, it’s also a good time to inspect the overall condition of the tool. Check if the blades are properly aligned and if the pivot bolt is secure. If the blades are misaligned, it could affect the sharpness and cutting efficiency.
Step 3: Lubricating the Blades
Once your pruners are sharp, it’s important to take one last step—lubrication. Lubricating the blades prevents rust and buildup from sap or dirt, which can make pruning more difficult.
How to Lubricate Pruner Blades
- Use a quality lubricant: Apply a light coating of lubricant to the blades. FELCO Tool Spray works well here too, as it prevents rust and helps keep the blades running smoothly.
- Wipe off excess: After applying the lubricant, wipe off any excess with a clean cloth. You want enough lubrication to protect the blades, but not so much that it collects dirt or debris.
Additional Tips for Pruner Maintenance
- Regular cleaning and sharpening: To keep your pruners in top shape, make cleaning and sharpening part of your routine maintenance. After each use, give the blades a quick clean, and sharpen them whenever you notice the cuts becoming less clean or precise.
- Replace worn parts: Over time, components like the spring or pivot bolt can wear out. Don’t hesitate to replace these parts if you notice a decline in performance. You can find a wide selection of replacement parts at Gemplers.
- Store pruners properly: When not in use, store your pruners in a dry location to avoid rust buildup. A well-maintained tool can last for years, and proper storage is key to preventing unnecessary damage.
Why Sharp Pruners Matter
Sharp pruners don’t just make your job easier; they’re also better for your plants. A sharp blade makes clean cuts, reducing the risk of crushing or damaging plant tissue. Clean cuts heal faster, helping plants stay healthy and vibrant. On the other hand, a dull blade can crush branches and leave ragged cuts, which invite disease and pests.
