To sharpen a very dull knife, use first the coarse and then the fine side of the whetstone; to sharpen a blade in better shape, use only the fine side. Have badly chipped or serrated knives professionally sharpened.
In this regard, are Wusthof knives 15 or 20 degrees?
(In fact, Wüsthof and Henckels discontinued their 20-degree knives.) To maintain that narrow edge, we use a tool specifically designed to sharpen a blade to 15 degrees. (We’ve also reviewed sharpeners designed for knives with 20-degree edge angles.)
Thereof, do you use coarse sharpener?
How do I know if my knife is 15 or 20 degree?
The best way to tell is by asking the manufacturer of the knife. As a general guide, European/American knives manufactured before 2010 have 20 degree edges while Asian style knives have 15 degree edges.
If the blade is made of carbon steel, after sharpening, clean the blades with water and then apply some cooking oil, to stop the surface rust forming. Put a coating of oil on it so it won’t rust. If this knife may be used for food, make sure the oil is edible.
