They therefore have what is called a symmetrical bevel. This obviously has an impact on the way the Western knife is sharpened.

You will also hear much about the angle of an edge when it comes to sharpening. With a Western knife, you must pay attention to the combined angle of each edge is the overall angle. Factory edges for Western knives range between 18 to 28 degrees. It is a figure far higher than that of the average Japanese style knife.

Western style knives are curved more

Western style knives also differ to Japanese in that many designs are curved along the blade. You utilise this design feature every time you rock your knife to and fro in a chopping action. The curve allows you to apply different amounts of pressure to specific areas of the blade.

This curved shape of Western style knives obviously means that you should check that it has the facility to sharpen your knife all the way along the curved edge when choosing which knife sharpener to buy.
