How to Sharpen Scissors

Check the scissors for dirt, rust, chips, bent tips or loose screws. In some cases, cutting performance issues are caused by dirt buildup or incorrect adjustment rather than a dull edge.

If possible, separate the blades by loosening the screw. Clean the blades using a soft cloth, warm water and mild dish soap. Remove adhesive residue using alcohol or a suitable cleaning product and dry the scissors thoroughly. Inspect the joint and inner blade surfaces for dirt, rust or burrs. Avoid removing material from the inner surfaces.

Use a sharpening stone or diamond sharpener and maintain the existing blade angle whenever possible. Work from the screw area toward the tip using smooth, controlled strokes. A few sharpening passes are often sufficient. Check progress regularly rather than removing excessive material.

After sharpening, gently remove the burr from the inner side of the blade using a fine stone. Take care not to alter the inner blade surface. This is one of the most common sharpening mistakes and may affect proper cutting contact.

Remove any remaining sharpening residue and wipe the blades clean. Apply a small drop of scissor oil to the joint and open and close the scissors several times. Reassemble the scissors and adjust the screw tension if necessary. The blades should move smoothly without excessive play.

Test the scissors using the material they are typically used for. Check whether the scissors cut cleanly from the tip to the pivot.

In many cases, yes. Proper sharpening can help restore cleaner and more precise cutting performance, depending on the condition of the scissors. Heavily worn or very dull scissors may require professional sharpening to restore optimal cutting performance.

That depends on how frequently the scissors are used and which materials they cut. Sharpen scissors when cutting performance starts to decline rather than following a fixed schedule.

Professional sharpening is often recommended for specialty scissors, damaged blades or situations where precise blade geometry must be maintained.

Yes. Using unsuitable tools, removing too much material or altering the blade geometry may affect cutting performance. One of the most common mistakes is changing the inner blade surface, which should generally remain unchanged.
