Masuda’s Blue 1 Damascus is a surprise item to us, not just because we see a knife with a texture and finish that is unique and stunning, but also we hear a name we didn’t expect in the world of knifemaking. Mr. Takeshi Masuda as the maker of this line is a very experienced blacksmith, but his expertise has been Kiridashi - a traditional single bevel woodworking and gardening tool. In fact, since he inherited the Masuda Kiridashi Factory as the second generation blacksmith, he has been forging Kiridashi for more than half a century and earned his title of Traditional Craftsman. We do stock his Kiridashi for quite a while so we are plenty surprised to hear he is switching to knifemaking.
Masuda san’s factory is located in the Sanjo region, and his knife does display some of the regional characteristics. The spine is not as thick as the typical Sanjo maker like Yoshikane or Tadafusa, but it still has a noticeable taper and holds its thickness until it reaches the tip. The surface receives a very polished Nashiji finish, where the cladding is shiny but the texture created by forging is kept, it almost looks like Takeshi Saji’s Diamond Damascus finish. The polish on the bevel is very refined, it’s a kasumi finish with a high grit polish, and unlike the typical texture we commonly see from Sakai knives, the scratch pattern on the core steel is more subtle and the soft iron appears to be more hazy and bright. This is a beautiful contrast created by a unique finishing process, its texturality and appearance reminds me of Hatsukokoro’s Komorebe with a natural stone finish.
Knives and Stones actually has some input on the grind of the knife, we happened to be in Hatsukokoro’s office when the first prototype of the line arrived in February of 2025. It had a Shinogi line that is quite lower than this final design, which means, at the same spine thickness, you would have quite more bevel thickness right after cutting into the food, leading to wedging and more cutting resistance. So we suggest Hatsukokoro with a different kind of grind. This new grind does keep the bevel nice and wide, combining with the generous tall profile, leads to a very choppy design. There is some thickness behind the edge so I say it is not the most smooth cutting knife out there, but a bit more strength is reassuring when doing large batch preps.
The one thing you need to be very careful about is the cladding. Despite the highly polished look, this is still an iron damascus cladding, which means the entire blade needs to be maintained to keep it from rusting. The price of the knife suggests that it is a product with a focus on the art and craft, but if you intend to use it, it won't let you down. I would also recommend it to collectors who like unique knives with interesting background stories.
