17 to 22 Degree Angles In fact, a 20 degrees angle is often considered the best sharing point for most knives. It is our experience that kitchen knives sharpened to 17 to 20 degrees cut very well and are still durable. For pocket or outdoor knives, a 20 degree angle would be on the low side of ideal.
For most knives, it is recommended to sharpen with an angle between 15° and 20°. If the recommendation differs by a few degrees, an approximation of the angle is not a problem. The blade's geometry will give you indications for choosing the right grinding angle.
Most kitchen knives are sharpened between 17 to 20 degrees angle. Different countries have their own sharpened angle, such as western knives falling into 20 to 22-degree angles. US knives are accurately sharpened at angles like 15 degrees, and their knives are sharpened on both sides.
On Wüsthof European-Style knives, the blade edge angle has been reduced to 28 degrees (14 degrees per side), while Asian-style Santoku, Nakiri and Chai Dao knives have a blade edge angle of 20 degrees (10 degrees per side).
German knives are sharpened at approx 20-22 degrees making the edge more durable but less prescise. The grit used here is commonly not above 800. The honing steel is used to true the edges of these blades. Japanese knives are made with a thinner blade and are ground to a more precise edge.
Renowned knife manufacturers like Zwilling, Wüsthof, Güde, Kai Shun, or Global usually recommend the 15 degrees grinding angle to sharpen the knives because it perfectly combines the stability of the blade and the sharpness of the edge.
The type of steel and the thickness of the blade determine how thin the cutting edge can be sharpened. Japanese knives often have a small cutting angle of approximately 15 degrees while a European knife has one of 20 degrees. Here we are talking about a sharpening angle per side.
Sharpening at a higher angle will tend to give you a less sharp edge, sharpening at a lower angle will greatly increase the time it takes to sharpen the knife. Maintaining a Consistent Angle - This is a fancy way of saying don't rock the edge when you sharpen.
While some stones – like those made of diamond or ceramic – can be used dry, they still usually benefit from a little water. Soaking the whetstone is important because it helps protect the stone from damage and wear. Sharpening your knives with a dry stone won't hurt the knife, but it will damage the stone over time.
Frequently Asked Questions. What is the sharpest knife material? Knives with an Obsidian blade are considered the sharpest in the world, but this material is not fit for making kitchen knives as they're extremely coarse and brittle.
The last step in sharpening is removing the burr – the hide side of an old leather belt will do, or buy a strop such as this one. A bit of baby oil on the leather will help you get a nice, even covering of the polishing compound. As with most things, you get what you pay for.
A kitchen knife should be sharpened every 1-2 months. Hone every week if you prefer a razor-sharp edge. For your professional chef's knife, you should have your knives professionally sharpened every 1-2 years. However, you might also still choose to sharpen them yourself every 2-3 months.
The 20° angle provides an excellent edge for kitchen cutlery and filet knives. It is a commonly used angle for higher quality blades, and possibly the most often used.
The blade- edge angle for all Zwilling J.A. Henckels cutlery, with the exception of santokus, is 15 degrees on each side (30 degrees total).
Over-sharpening a knife can actually damage the edge and make it duller. It's important to sharpen a knife only when it needs it, and to sharpen it to the correct angle.
A 17 to 20 degree angle covers most kitchen knives, pocket knives, and outdoor knives. Some knives (typically Japanese manufacturers) will sharpen their knives to roughly 17 degrees. Most western knives are roughly 20 degrees. In fact, a 20 degrees angle is often considered the best sharing point for most knives.
The short answer is yes, a knife can be too sharp.
Both styles provide their own set of benefits. German knives are thicker and heavier to provide added strength and durability for your heavy-duty chopping, while Japanese knives are made of carbon-rich steel for a lightweight blade and razor-sharp edge that offer edge retention and ultimate control and precision.
European (German) Knife Specs
The blade is thicker, more robust especially towards the bolster which they often have. The hardness of the steel can vary but typically they are softer than Japanese knives at around 55 to 60 HrC Rockwell.
If you are looking for a general-purpose knife then we recommend going for the 20-degree option, but if you want a knife that is going to be able to handle more delicate tasks such as slicing fruits and vegetables then the 15-degree option might be better.
