What is the best thing to sharpen a knife with?

Use a knife sharpener specifically designed for the task. These tools come in various forms, including electric sharpeners, whetstone sets and handheld sharpeners. Each type has its advantages, but the key is to choose a sharpener that suits your specific needs and knife types.

For instance, an electric sharpener like Smith's Electric Knife Sharpener is great for quick and precise sharpening, while a whetstone set like the Iki Ruixin Pro Sharpener offers more control and versatility.

Is it better to sharpen a knife wet or dry?

It depends on the type of sharpener you're using. Whetstones, for example, are often used wet. The water helps to lubricate the stone, reducing friction and making the sharpening process smoother. On the other hand, electric and handheld sharpeners are typically used dry. Always follow the manufacturer's instructions for the best results.
