• 2 different edge angles. For example, 17° for kitchen knives and 25° for hunting and outdoor knives.

• 2 different sharpening inserts: The carbide inserts in the coarse, dark slot are for basic sharpening. The ceramic inserts in the fine, white slot are for finehoning of the blade and restoring the original sharpness.

• Hold the knife sharpener in the ribbed area with one hand and press it onto a firm surface where it won’t slip. Draw the knife through the sharpener three or four times without applying force. It will then be ready to use again.

• Not suitable for serrated, jagged or damaged blades!
