How do you sharpen your knife? A lot of past sushi class participants asked me. I am trained to use traditional whetstones.
I use both medium grade and finishing stones like these.

Just like most Sushi techniques, the knife sharpening technique is very simple to demonstrate, but it's very difficult to master (or, takes some practice). It's just like learning how to play guitar. So, my advice to you is to get an automatic knife sharpener.

We did. Does it sound like cheating? No, not at all because we recently bought this and we use it to sharpen all our 30+ knives. The result? Wonderful. The best part for us was it was such a time saver. We used to spend at least an hour or two sharpening our knives using whetstones. With this automatic sharpener, it took us about forty minutes! That's worth every penny. And it was only $22.95!
