It is surprising to many that the number one cause of kitchen accidents is a dull knife, not a tool malfunction, or some other inevitable incident. If your knife has a blunt tip, it can easily slip and cause you harm. Hence, sharpening your knife is a safety issue that should not be ignored. Anytime you see your blades become dull, it's time to check the quality and hone it back to an acceptable level.
There are different ways to sharpen your knife, each with its advantages and disadvantages.
The most modern way to sharpen your knife to perfection with an electric knife sharpener. In contrast to wet stones, electric knife sharpeners offer razor-sharp blades which, depending on the type of knife used, are even better than factory edges in some cases. With an electric knife blade, you don't have to worry about the correct angle of the sharpening or other details that you should know when sharpening a knife by hand, as most knife sharpeners come with predefined angle guides and instructions to use.

The second option is to sharpen knives by hand using traditional stone or steel. This was the de facto rule of sharpening your knives for a long time, and there are still people out there who you might be able to dedicate to the art of sharpening knives with stones. This method is very affordable but it takes a lot of time to master the actual sharpening skills and process. For those who have a lot of free time and want to give it a try, this is a great alternative.
