Key Features to Look For

When you shop for a knife sharpening machine, keep these features in mind:

  • Type of Sharpening System:
    • Electric Sharpeners: These are fast and easy to use. They have slots where you pull the knife through.
    • Manual Sharpeners: These often use stones or rods. They give you more control but take more time.

Important Materials

The materials used in a knife sharpener affect its durability and how well it works.

  • Sharpening Abrasives:
