This knife by Itsuo Doi is a beautiful piece of craftsmanship with a rustic but polished look. It's heavy and quite hefty with a thick spine, but it doesn't feel thick behind the edge and cuts like butter. I liked the K tip and it worked well to brunoise garlic although I probably wouldn't use it for an extended prep session due to the weight. It remains thick throughout most of the knife with only a small amount of distal taper. I will probably lean towards using this knife on proteins rather than vegetables.
Decent out of the box edge, maybe a 6-7/10. The blue #2 treat seems excellent though, and I imagine this will be a joy to sharpen when the time comes.
The iron cladding hasn't seemed to react much visually yet, although I can smell it reacting when cutting certain things. I imagine that will diminsh over time as a patina develops.
All things considered, I am happy to add this knife to my collection.
