From ancient times, waterstones have been used for sharpening Japanese cutlery such as Samurai swords, knives and scissors.
In present, you may have used knife sharpener. However, sharpeners are completely different from waterstones.
Actually, sharpening by sharpeners impairs cutting edge of knives. Eventually, those knives will become unable to recover their cutting performance.
If you think you want to enjoy high cutting performance of your knife, then we highly recommend you to use waterstones.
Why You Should Use Waterstones, Not Sharpeners?
When you sharpen your knife, you need to shave edge of the knife and make it thin and sharp. In other words, you need to recover its cutting edge back somehow to its original shape.
Sharpeners DON’T sharpen cutting edges of the knives. Sharpeners scratch edges and make them jagged. Because knife’s edges become jaggy, it just seems to cut better.
However, jaggy edges made by sharpeners don’t last long. These jags are ground off soon as you cut foods. After all, edge of the knife become flat again but thick! Therefore, cutting edges become dull by using sharpener repeatedly.
It may be okay to use sharpeners for a couple of times. However, you need to sharpen by waterstones in order to make your knife’s cutting edge thin and sharp. Otherwise, edge of the knife changes its shape and unable to recover!
