The Step-by-Step Sharpening Process
This process provides a general overview. Specific techniques may vary depending on the type of shears and sharpening equipment used. Always consult the manufacturer’s instructions for your specific equipment.
- Cleaning and Inspection: Thoroughly clean the shears to remove hair and debris. Inspect the blades for damage, nicks, or bends.
- Disassembly (Optional): If necessary and comfortable, disassemble the shears for better access to the blades. Note the original configuration for reassembly.
- Sharpening the Bevel: Using the appropriate grit sharpening stone and lubricant, carefully sharpen the bevel (angled edge) of each blade. Maintain the original angle of the bevel and use consistent pressure.
- Honing the Edge: After sharpening, use a honing steel to realign the blade edge and remove any burrs. Use light, consistent strokes.
- Reassembly (If Disassembled): Carefully reassemble the shears, ensuring proper alignment and tension.
- Lubrication: Apply a small amount of shear oil to the pivot point and along the blades to ensure smooth operation.
- Testing: Test the shears on hair (human or synthetic) to evaluate their sharpness. Make adjustments to the sharpening process if needed.
Common Mistakes to Avoid During Shear Sharpening
Avoiding these common mistakes will help prevent damage to your shears and ensure a successful sharpening process:
- Incorrect Angle: Failing to maintain the original bevel angle can damage the cutting edge.
- Excessive Pressure: Applying too much pressure can remove too much material and create an uneven edge.
- Dry Sharpening: Sharpening without proper lubrication can generate excessive heat, damaging the blade steel.
- Neglecting Honing: Skipping the honing process can leave burrs on the edge, resulting in a less effective cut.
- Improper Reassembly: Incorrect reassembly can cause the shears to bind or not cut properly.
Maintaining Shear Sharpness Between Sharpenings
Regular maintenance can extend the life of your shears and minimize the need for frequent sharpening.
- Daily Cleaning: Clean shears after each use to remove hair and debris.
- Regular Lubrication: Apply shear oil to the pivot point and along the blades daily.
- Proper Storage: Store shears in a case or pouch to protect them from damage.
- Avoid Dropping: Dropping shears can damage the blades and disrupt their alignment.
Troubleshooting Common Shear Problems
Addressing these common shear problems can help you maintain their performance:
- Hair Folding: Indicates dull blades or improper tension.
- Binding: Indicates improper lubrication or alignment.
- Nicks or Chips: Requires professional repair or replacement.
Choosing a Professional Shear Sharpener
If you are uncomfortable sharpening your own shears, or if they require significant repair, consider using a professional sharpening service.
- Experience and Reputation: Choose a sharpener with a proven track record and positive reviews.
- Equipment and Techniques: Ensure the sharpener uses appropriate equipment and techniques for your type of shears.
- Guarantee: Ask about a guarantee or warranty on their work.
Tools for the Barber Trade
Knowing how to keep the tools of your trade in prime condition is just as important as being able to cut hair. Understanding this process ensures your clients will have a positive experience.
Frequently Asked Questions
What is the best type of sharpening stone for barber shears?
The “best” type depends on the condition of your shears and your sharpening skills. Combination stones with a coarse side for reshaping and a fine side for polishing are a good starting point. Diamond stones are very aggressive and effective for removing material quickly, but require a delicate touch. Ceramic stones offer a good balance of sharpening speed and precision.
How often should I sharpen my barber shears?
The frequency of sharpening depends on usage, hair type, and the quality of your shears. As a general rule, sharpen when you notice the shears beginning to pull, snag, or require more force to cut. This could be as often as every few weeks for heavy users or every few months for light users.
Can I use regular oil to lubricate my barber shears?
No. Use only shear oil specifically designed for barber shears. Regular oils can be too thick and may contain additives that can damage the blades or attract debris. Shear oil is lightweight, non-gumming, and formulated to protect the delicate cutting edges.
How do I know if my shears are properly aligned?
Proper alignment is crucial for efficient cutting. Check for alignment by holding the shears up to a light source. The blades should meet evenly along their entire length. If there are gaps or uneven pressure, adjust the pivot screw or seek professional assistance.
What is the correct bevel angle for my barber shears?
The bevel angle varies depending on the type of shears. Most barber shears have a bevel angle between 40 and 45 degrees. Maintain this angle during sharpening to preserve the cutting edge’s integrity. Consult the manufacturer’s specifications if available.
What does “honing” actually do for the blades?
Honing realigns the blade edge after sharpening. Sharpening can leave microscopic burrs or irregularities on the edge. Honing removes these burrs, creating a smoother, sharper, and more durable cutting edge. Think of it as polishing and refining the edge.
Can I use a power grinder to sharpen my barber shears?
While power grinders can be used, they are not recommended for beginners. The high speed and heat generated by a grinder can easily damage the shears if you are not experienced. Stick to manual sharpening techniques until you have mastered the basics.
What is the best way to test the sharpness of my barber shears?
The best way is to test them on hair, both human and synthetic. The shears should cut cleanly and smoothly without pulling or snagging. Another method is the “tissue paper test.” Sharp shears will slice through tissue paper easily, while dull shears will tear it.
What if I accidentally scratch or nick the blade during sharpening?
Minor scratches can often be removed with finer grit sharpening stones. However, significant nicks or chips may require professional repair or blade replacement. Attempting to grind away large defects yourself can damage the shears further.
How can I prevent my shears from rusting?
Rust is a common enemy of shears. Keep them clean and dry. Always wipe them down after use. When storing, apply a light coat of shear oil to protect the blades from moisture.
What does ‘shear tension’ refer to, and why is it important?
Shear tension refers to the pressure between the two blades. Correct tension allows the shears to cut smoothly and efficiently without folding or binding the hair. Tension that is too loose will cause the hair to fold. Tension that is too tight will cause the shears to bind and wear out quickly. Adjust the pivot screw to achieve the correct tension.
Are left-handed shears sharpened differently from right-handed shears?
The sharpening process for left-handed and right-handed shears is essentially the same, the direction of the strokes across the sharpening stone are determined by which hand you use. The angle of the bevel and the overall technique remain consistent. Just remember you are looking to sharpen the same edge on each blade and the sharpening stroke mirrors which hand holds the shears.
