The Knife

The Finest of German & Japanese Knife Crafting

  • If you asked us which two countries are globally known for producing the best knives, we would say without a doubt that it is Japan and Germany.
  • Both nations have ancient knife crafting traditions that are woven deeply into their respective cultures.

Perfectly Balances European Utility & Asian Beauty

  • Doitsujin was crafted using world-renowned German stainless steel and finished with the classic century-old Japanese techniques. It was designed with the intention of being the ultimate hybrid tool.
  • It perfectly combines the best practical features of German and Japanese blade making styles. This is even apparent with the translation of the knives name "Dogisujin" which means "The German" in English.

It Challenges the Stereotype

  • Historically, Deba knives were designed to be the ultimate fish tool. They’re used for sectioning, gutting, and filleting all different sizes and types of fish.
  • However, the European qualities of Doitsujin provide some subtle differences, that allow it to have a much more diverse range of applications.
  • One of these differences is the full tang, which adds more weight and leverage to the blade. This enables you to use the knife with more of a cleaving motion, to handle tasks like quickly prepping large amounts of bulk veggies.

Not Just For Fish

  • The sheer strength of the tempered German steel also allows you to be much less delicate with Doitsujin’s blade.
  • Any Japanese chef would agree that you would never use a traditional Deba knife for cleaving through dense surfaces, such as poultry bones, for fear of chipping the knives delicate edge.
  • But the rigidity of the German steel effortlessly silences these fears and allows you to cut straight through all kinds of small bones with ease.

A Sophisticated Cutting Experience

  • Doitsujin was explicitly designed to allow for a Japanese style single beveled edge, as well as a European inspired double-tapered blade shape.
  • Its unique blade profile and weighting makes you adopt a slightly different cutting form than you may be used to.
  • Many people have found this to be refreshing, as it provides a different kind of knife experience, one that we see many chefs are starting to prefer over conventional fish and veggie knives.

A Knife to Test the Ages

  • At Masuta Knives, we appreciate and love cutlery more than almost anyone.
  • But every once in a while, we find a knife that genuinely reinvigorates our kitchen experience. Doitsujin was that blade for us this year, and we’re so excited that we can share it with the world now too.
  • We can confidently say that this knifes creators have perfectly combined the blade crafting methodologies of the German and Japanese people.
  • Not only is Doitsujin an exceptionally beautiful knife, but it’s by far one of the most durable blades on the market today.

Carefully Packaged by Hand

  • All of our knives are shipped in protectively padded cardboard boxes.
  • This is to ensure that your blade stays safe on its journey to you.
  • Many of our customers also choose to use the original packaging to store their knives in between uses.

Not Dishwasher Friendly

  • We perform extensive durability testing on all our knives before we agree to share them with our wholesale or online customers.
  • This is to ensure that we provide the highest quality products that will last the longest.
  • So, this means that if you’re in a pinch, yes you can put a Masuta knife in the dishwasher. One gentle wash cycle won’t be enough to cause permanent harm to the edge, handle, or tone of your knife.
  • However, please keep in mind that most dishwasher powders and detergents contain highly alkaline compounds such as trisodium phosphate.
  • Long-term exposure to these chemicals will eventually start to degrade the handle, and "decarbonize" the tone of your blade. This is why professional Chefs always hand wash their knives.
  • We do provide industrial grade knives capable of withstanding commercial foodservice environments as part of our wholesaling business. Please visit our wholesale page for more information.

Sharpen As Needed

  • All of our knives are specifically forged so that they have a long-lasting, durable edge.
  • For a home cook, they stay razor-sharp for many months and possibly up to a year!
  • For a professional Chef who is using the knife multiple times a day, its edge can last for up to three-months between sharpening.
  • For the best results when re-sharpening, we recommend you use a series of whetstones with different grits. You can also use a sharpening rod of your choice.
  • Electric sharpeners are usually okay too, as long as they are high-quality ones.
  • Each knife also comes with a sharpening guide and recommended sharpening angles as part of the Masuta Certificate of Authenticity.

Please be Careful

  • Our knives are built to hold a lasting, razor-sharp edge. Please remember to be cautious when using your knife and to keep children away.
  • We also take the time to pre-sharpen all of our knives by hand before we send them to you. This is so your knife will be able to shave through thin strips of paper right out of the box!
  • Although doing this is very fun and satisfying (we do it too), please remember to be careful and not to get too excited when you first get your knife. Masuta Knife Imports is not responsible for any injuries that may result from improper or unsafe handling of your knife.
  • All of our blades are beautiful and unique. However, they can also be dangerous, and they must be respected as such.
