Designed for European and Asian-style knives. Two stages of edge care for both knife styles.
Soft ergonomic handle creates a comfortable and secure grip. Rubberized slip-resistant base for safe use. Made for left and right handed use.
HOW TO SHARPEN YOUR KNIFE: 1. Place sharpener on a flat, dry surface. 2. Use the Coarse slot to sharpen your knife’s edge. Use the Fine slot to polish and hone your knife’s edge.
Firmly hold the sharpener by the handle and place the heel of your knife into the sharpening slot. Pull the knife back towards you from the heel to the tip of the knife’s edge with light pressure downwards. As you pull the knife backward, follow the curve of the blade to ensure the knife’s edge is in constant contact with the sharpening rods. Repeat 8-10 times depending on how dull or damaged the knife is at the start. Never push the knife forward through the sharpening slot.
When you are finished sharpening your knife, clean the sharpener with a damp cloth or soft brush and dry immediately.

The Cangshan team spent 16 months doing R&D, finalizing the industrial-Grade carbide sharpening components to ensure that this knife sharpener can work effectively on high alloy metal blades.
Professional 3-1 knife sharpener with built in angle adjustment from 14 to 24 degree, offering the correct blade angle to expertly maintain the cutting edges of both Western- and Asian-style knives. Also includes unique ceramic sharpening blade slot designed to sharpen 2-Piece kitchen shears.
Offers two stages of sharpening for each knife style: a coarse ultra-hard Tungsten carbide side for restoring edges to dull blades and a finely grained ceramic side for honing and finishing edges (also useful for quick touch-ups).
A unique handle-shaped grip helps keep fingers safe, and a nonslip rubberized base provides stability on the work surface.
Not for use with serrated knives or blades sharpened on only one side of the cutting edge, such as sashimi knives.

The 9-inch Honing Steel features a half-grooved and half-smooth finish. The grooved, coarse side of the steel is used for regular maintenance, to realign the microscopic teeth on the blade’s edge. The smooth, fine side of the steel is used to finish the edge with a few swipes of the blade after honing on the grooved side. For average use, the grooved side can be used weekly and the smooth side, daily. Regularly honed knives will retain their edges longer before needing to be sharpened.
