An ULU knife has a special curved blade. Keep it at its best with a sharpener that's made for it.
Diamond-sharpened carbide inserts help you maintain the blade and keep it sharp

How to Sharpen
Start from one tip and lightly move the carbide edge on the bevel side of the blade and the metal guide on the back or flat side of the blade.
Repeat until you get it to the desired sharpness.
Finally, very lightly, reverse using the carbide edge on the back and the metal guide on the bevel. (This removes the small burr you created and gives you the sharpest edge.)
