Knife Sharpeners restore the beveled edge back to the correct angle specifications for the cutting utensil.
What determines the angle is what you will use the knife for. The larger the bevels angle the more durable it will be and the longer the knife blade will last between sharpening. The shallower the bevels angle the sharper and more delicate it will be but the knife blade will require sharpening more often. There are many suitable angles for a beveled knife edge to have but not all are suitable for basic kitchen cutlery.
For example, an 11-degree bevel angle is the narrowest and is used to put a razor-sharp edge on fine-cutting tools, like X-acto blades, woodcarving instruments and other specialty tools. This angle will require the most frequent re-sharpening. Usually X-acto blades are so economical price you can easily dispose of them and replace the blade when it gets dull. Then there is the 15-degree bevel angle and it is most suitable for fillet, boning and uses that require exceptional sharpness and a bit more durability.
For kitchen cutlery the 19-degree bevel angle is recommended. When selecting a knife sharpener it is important to choose one that will restore the kitchen knife to the correct angle. It is also important to have a knife sharpener that is convenient to use so you feel like sharpening your knives often so that spend less time on cutting task and your knives cut better. It is not important for a kitchen knife sharpener to provide a super polished edge. A super polished edge does not slice and dice best for food processing duties required by the chef.
The 22-degree bevel angle provides a wider, more durable edge that is suitable for pocket knives, fixed-blade hunting knives and serrated-blade knives. The 25-degree bevel angle is the widest, producing the longest lasting edge for utility knives, like carpet, linoleum and electrician’s knives.
