How to Remove a Burr

Based on our substantial hands-on sharpening experience, finish sharpening by removing weakened metal from the apex.

A Repeatable Sharpening Sequence

Inspect the edge first. Decide whether you are repairing geometry or merely renewing sharpness. Establish the bevel, work until the abrasive reaches the apex, reduce pressure as the edge develops, remove the burr and then verify the result. The equipment can change; that logic remains dependable.

A Practical Step-By-Step Method

1. Inspect: identify chips, rounding, skew and the existing bevel before removing steel.
2. Set the geometry: match a useful existing bevel or deliberately choose a new one for the tool's work.
3. Sharpen: use controlled pressure and cover the abrasive evenly rather than dwelling in one spot.
4. Watch the apex: use burr formation, marker removal and visual checks as feedback.
5. Refine: reduce pressure and move to a finer abrasive only after the previous stage has done its job.
6. Deburr: remove weakened metal from both sides of the edge.
7. Record: if a jig is involved, note the settings that produced the geometry you want to repeat.

Use Feedback Instead Of Fixed Stroke Counts

Sharpening is easier to control when each stage has an observable completion condition. During shaping, the geometry must be correct. During sharpening, the abrasive must reach the apex. During refinement, the coarse scratch pattern should be replaced to the degree the tool needs. During deburring, the weakened metal at the edge must be removed. A fixed number of strokes cannot guarantee any of those outcomes.

Pressure should generally decrease as the edge becomes more refined. Heavy pressure is useful only when there is a material-removal problem to solve; near the finished apex it can enlarge the burr, over-remove steel and make consistency harder.

Keep A Simple Sharpening Record

For repeat tools, note the angle, jig projection or support setting, abrasive sequence and any geometry detail that matters. A small record turns future sharpening into maintenance rather than rediscovery. It is particularly useful for turning tools and jigs, but the same idea works for chisels, plane irons and knives.

Common Mistakes To Avoid

• Changing a useful bevel simply because another angle is popular.
• Using heavy pressure after the abrasive has already reached the apex.
• Skipping deburring and mistaking a wire edge for lasting sharpness.
• Adding finer grits before the previous abrasive has completed its job.
• Failing to record jig settings, then reshaping the tool during every touch-up.
