5 Common Mistakes with Burr Formation & Deburring Stropping (And How to Avoid Them)

As a passionate cutlery sharpener, I spend countless hours in my workshop perfecting the art of creating and maintaining razor-sharp edges. While there’s a certain satisfaction in achieving that level of sharpness, I’ve learned that burr formation and the subsequent deburring process can be tricky. Over the years, I’ve encountered my share of mistakes, and I want to share my experiences with you to help you sidestep some of the common pitfalls in burr formation and deburring stropping.

Mistake #1: Not Understanding Burr Formation

When I first started sharpening knives, I thought the burr was just an annoying byproduct of the sharpening process. However, I quickly learned that the burr actually plays a major role in achieving a sharp edge. A burr is formed on the opposite side of the edge being sharpened, and it indicates that you have effectively reached the apex of the blade.

How to Avoid This Mistake:

Make sure to create a consistent burr along the entire edge of the blade. When sharpening, focus on maintaining the same angle (usually between 15 to 20 degrees for most kitchen knives). I often switch sides every few strokes to ensure a uniform burr formation. If you're unsure about angles, investing in a sharpening guide can be a major difference maker, typically costing around $20 to $50.

Mistake #2: Rushing the Deburring Process

I’ve been guilty of wanting to see results too quickly. After forming the burr, I would often hastily move on to deburring. This impatience led to inconsistent edges and frustratingly dull knives.

How to Avoid This Mistake:

Give yourself the time required for deburring. I typically spend about 5 to 10 minutes on this phase, which involves using a finer grit waterstone (around 1000 to 3000 grit) or a leather strop with compound. The trick is to gently remove the burr without altering the angle of the edge. Slow, deliberate strokes help maintain the sharpness while effectively removing that pesky burr.

Mistake #3: Using the Wrong Strop Material

In my early days of sharpening, I used whatever scrap leather I could find for stropping. While this can work in a pinch, the material quality can greatly affect the final result. I learned the hard way that a good-quality strop makes a difference.

How to Avoid This Mistake:

Invest in a high-quality strop, ideally made from vegetable-tanned leather. A good strop usually ranges from $30 to $100, depending on the size and quality. I also recommend using a strop that’s at least 2 inches wide. This width allows for more surface area and better control during stropping.

Mistake #4: Overusing Stropping Compound

When I first started using stropping compound, I thought, “More is better!” Unfortunately, I ended up with a sticky mess on my strop and a less-than-ideal edge. Overapplying the compound can clog the leather and create inconsistencies.

How to Avoid This Mistake:

Less is more when it comes to stropping compound. I’ve found that a small amount (a pea-sized dot) is sufficient for a full-length strop. Apply it sparingly, and remember to rub it in evenly. A good compound typically costs around $10 to $20 and can last for many sessions.

Mistake #5: Ignoring the Angle During Stropping

One of my initial misconceptions was thinking that stropping was just a casual wipe along the strop. I didn’t pay close attention to the angle, and as a result, I often dulled my edge instead of sharpening it.

How to Avoid This Mistake:

Maintain the same angle you used during sharpening while stropping. For most knives, this means keeping the blade flat against the strop at the same angle as your sharpening. I recommend practicing this on a less valuable blade until you feel comfortable. Remember, slow and steady wins the race.

FAQ

What is burr formation?
Burr formation is the process of creating a small, thin flap of steel on the opposite side of the blade edge during sharpening, indicating that you've reached the apex.
How often should I strop my knife?
I typically strop my knives after every few uses, or whenever I notice a slight dullness. Regular stropping helps maintain the edge without needing to resharpen frequently.
Can I use any leather for stropping?
While any leather can technically work, high-quality vegetable-tanned leather will yield the best results. It provides better support and allows for more effective compound application.
What this comes down to: mastering the art of burr formation and deburring stropping takes practice and patience. By avoiding these common mistakes, you'll find yourself with sharper, better-performing blades in your kitchen or workshop. Remember, honing your skills is a journey, and every mistake is a lesson learned. Happy sharpening!
