  • Rated 5 out of 5 by from Back to new! Received this as a gift, as I have a full compliment of Shuns. After using a whetstone previously, I must say this is just as efficient. I tried it with my kiritsuke which has had a ding in the edge for some time (unfortunate sink drop). After a few runs through, then a quick honing, it was at factory new. Great product as always, KAI! (Note: keep in mind, it DOES require a quick honing. Not an issue, but be aware.)
