Swiss Istor Duplex Sharpener

The carbide tip on the Duplex Sharpener is used in the same way as the Standard and Professional models (see above).

In addition, the Duplex Sharpener is equipped with a diamond-coated steel sharpening device that can be used to remove nicks and bumps in a blade. Using it on its flat side, gently grind out nicks and burrs in a rotating or straight motion, holding it at the desired bevel angle. See above for the suggested angles for different uses.
