How to Sharpen Fiskars Shears?
Sharpening Fiskars shears effectively restores their cutting power. This involves cleaning the blades, securing them, and using an appropriate sharpening tool, like a diamond file or a specific Fiskars sharpener, applying consistent pressure at the correct angle, and then cleaning and lubricating the blades.
Understanding the Importance of Sharp Shears
Fiskars shears are renowned for their durability and efficiency, making them a staple in gardens, craft rooms, and households. However, even the best shears lose their edge over time. Using dull shears can lead to torn foliage, frayed fabric, and ultimately, wasted effort. Regularly sharpening your Fiskars shears not only restores their cutting precision but also extends their lifespan, saving you money in the long run.
The Benefits of Maintaining Sharp Blades
- Clean Cuts: Sharp blades ensure clean, precise cuts that are essential for healthy plants and professional-looking crafts.
- Reduced Strain: Sharp shears require less force, reducing hand fatigue and preventing injuries.
- Extended Lifespan: Proper sharpening removes minor imperfections and prevents further damage to the blades.
- Cost-Effectiveness: Sharpening is a far more economical option than replacing shears.
Tools Required for Sharpening
Before you begin, gather the necessary tools. Having everything prepared will streamline the sharpening process and ensure safety.
- Cleaning Supplies: Warm water, dish soap, and a clean cloth or brush to remove debris.
- Sharpening Tool: A diamond file, a Fiskars sharpener, or a whetstone are excellent choices. Avoid harsh grinding wheels as they can damage the blades.
- Lubricant: Light machine oil or mineral oil to protect the blades after sharpening.
- Safety Gear: Work gloves to protect your hands, and eye protection to guard against metal shards.
- Vice (Optional): A vice can help secure the shears for easier sharpening.
The Sharpening Process: Step-by-Step
Sharpening Fiskars shears is a straightforward process that can be accomplished in a few simple steps.
- Cleaning the Blades: Thoroughly clean the blades with warm, soapy water to remove dirt, sap, and any other residue. Rinse and dry completely.
- Securing the Shears: If using a vice, carefully clamp the shears in place, ensuring they are secure but not overly tightened. This will provide stability during sharpening. If not using a vice, hold the shears firmly in one hand.
- Sharpening with a Diamond File: Hold the file at the original bevel angle of the blade (usually around 20-30 degrees). Apply consistent pressure as you draw the file along the cutting edge, moving from the base of the blade to the tip. Repeat this process 5-10 times on each blade, maintaining the angle.
- Sharpening with a Fiskars Sharpener: Follow the manufacturer’s instructions for your specific Fiskars sharpener. Typically, this involves inserting the blades into the sharpener and running them through a few times.
- Deburring (Optional): After sharpening, there may be a slight burr along the cutting edge. Use a fine-grit honing stone or a piece of leather to remove this burr.
- Lubricating the Blades: Apply a light coat of machine oil or mineral oil to the blades to protect them from rust and corrosion.
- Testing the Sharpness: Test the shears on a piece of paper or fabric to ensure they are cutting cleanly. If necessary, repeat the sharpening process.
Common Mistakes to Avoid
- Using Excessive Force: Applying too much pressure can damage the blades and make them uneven. Use moderate and consistent pressure.
- Incorrect Angle: Failing to maintain the correct bevel angle will result in a dull or uneven edge.
- Skipping the Cleaning Step: Sharpening dirty blades can scratch the surface and damage the sharpening tool.
- Neglecting Lubrication: Failing to lubricate the blades after sharpening can lead to rust and corrosion.
- Using Inappropriate Tools: Avoid using harsh grinding wheels, which can overheat and weaken the steel.
Maintaining Your Sharpened Shears
Regular maintenance is crucial for preserving the sharpness of your Fiskars shears.
- Clean after each use: Wipe down the blades with a damp cloth to remove sap and debris.
- Lubricate periodically: Apply a light coat of oil to the blades to prevent rust.
- Store properly: Store your shears in a dry, clean place to protect them from damage.
- Sharpen regularly: Sharpen your shears every few months, or more frequently if you use them often.

Frequently Asked Questions
1. How often should I sharpen my Fiskars shears?
The frequency of sharpening depends on how often you use your shears. As a general rule, sharpen them every few months for light use, or more frequently (every few weeks) for heavy use. If you notice the shears are struggling to cut cleanly, it’s time to sharpen them.
2. Can I use a regular knife sharpener on my Fiskars shears?
While some knife sharpeners may work, it’s best to use a sharpener specifically designed for shears or a diamond file. Knife sharpeners may not have the correct angle or surface to effectively sharpen the blades of shears.
3. What is the correct angle for sharpening Fiskars shears?
The correct angle typically ranges between 20 and 30 degrees. Observe the original bevel of the blade and try to maintain that angle during sharpening. Experimenting to find the angle that gives you the best performance is sometimes necessary.
4. Is it possible to over-sharpen my shears?
Yes, it is possible to over-sharpen shears. Over-sharpening can weaken the blades and make them brittle. Avoid applying excessive pressure or sharpening too frequently.
5. Can I sharpen serrated Fiskars shears?
Sharpening serrated shears requires specialized tools and techniques. It’s best to consult a professional sharpener or purchase a serrated blade sharpener designed for this purpose.
6. How do I know if my shears are sharp enough?
A sharp pair of shears will cut cleanly and effortlessly through paper, fabric, or plant stems. If the shears are tearing or requiring excessive force, they need sharpening.
7. What type of oil should I use to lubricate my shears?
Use a light machine oil or mineral oil to lubricate your shears. Avoid using vegetable oil or other cooking oils, as they can become sticky and attract dirt.
8. What if I damage my shears during sharpening?
If you accidentally damage your shears during sharpening, you may be able to repair minor imperfections with a honing stone or by consulting a professional sharpener. However, severe damage may require replacing the blades or the entire tool.
9. Can I use sandpaper to sharpen my Fiskars shears?
Sandpaper is not the best tool for sharpening shears, as it can be too abrasive and difficult to control. Diamond files or sharpening stones are preferable.
10. How do I clean rust off my Fiskars shears?
You can remove rust from your Fiskars shears by soaking them in vinegar for a few hours, then scrubbing the rust away with a steel wool pad or a wire brush. Rinse and dry the blades thoroughly, and apply a coat of oil to prevent future rust.
11. Can I use a drill with a sharpening attachment to sharpen my shears?
While a drill with a sharpening attachment might seem convenient, it can easily overheat and damage the blades of your Fiskars shears. This method is generally not recommended, especially for beginners. Stick to manual sharpening methods for better control.
12. Are there any safety precautions I should take when sharpening shears?
Always wear work gloves to protect your hands from cuts and abrasions. Eye protection is also recommended to guard against metal shards. Work in a well-lit area and maintain a stable grip on the shears and sharpening tool. When using a vice, ensure it is securely mounted and that the shears are properly clamped.
