Keep it sharp
I wasn't sure how to use it at first. Then, I remembered the stone came with a QR code you scan to access a very helpful video on how to use the stone. The video had clear instructions. I recommend the stone to keep your blades sharp, especially if you cook a lot!

Seems Generic
With Katto's image in mind I was disappointed that this product instantly appeared to be some 'bought-in' rip off. I have other Katto products which I love but this is nothing special. Even the wooden base which is something you'd expect Katto to be well-equipped to manufacture certainly seemed below par and out-sourced with no finesse. I think they really missed an opportunity to add their touch. The product does the job but I'd recommend (for this product only) going elsewhere for cheaper.
