Burja [pronounced as 'booryah'] is a prosciutto knife. Burja is a knife of our own creation - we love good knives, we love good prosciutto, and good prosciutto should be sliced by hand using the sharpest knife around.

Burja is the first Japanese-made prosciutto knife. Designed by SharpEdge, forged by Japanese smithy Suncraft, based in the famous blacksmith town of Seki, made of Japanese steel and optimized for cutting prosciutto. No one has ever paid so much attention to making a knife that will meet all the needs of cutting prosciutto. It is especially difficult to make a universal knife since there are a lot of different types of prosciutto, as well as there are many cutting techniques to slice it. But no worries - Burja is not just a knife for cutting prosciutto. Because of its harder, but still flexible blade, it can be used for cutting other dry meats as well. And due to its thin and long blade profile, it will perform well as a slicer for larger pieces of meat and fish.

Burja knife is a combination of the rich culinary tradition of prosciutto ham with the Japanese tradition of forging knives. Since Japanese blacksmiths are the best blacksmiths in the world, possessing centuries of knowledge and experience of forging steel, it made perfect sense to make our prosciutto knife in Japan. From idea to design, after many conversations with knife makers, trial&errors, finding the right steel and handles, many sliced (and eaten) prosciuttos, visits to Japan, the process finally ended after a good two years.

What does Burja mean?
Burja is a Slovenian name of the local wind, in English known under the name Bora. Burja wind is typical for the Adriatic region. It is a cold, dry, strong and gusty northeast wind without which no prosciutto would ever be produced, no matter where in the world it is dried. With all the characteristics, Burja immediately felt like the perfect name for our prosciutto knife. Three engraved symbols can be seen on the left side of the blade. These symbols are called wind barbs, they indicate wind direction and wind speed. The three engraved wind barbs represent Burja wind with three different wind speeds, as Burja is a gusty and very strong wind.

    The shape of Burja is unique, although at first sight resembles other prosciutto knives. It has an extremely thin spine of the blade at 1.8mm. The blade is 300mm (11.8") long and finishes with a thin, pointy tip, revealing its origins and traditions of blacksmiths that were once forging katanas.

    The Aichi steel Burja is suitable for the softest prosciutto because it has the most flexible blade and is made from the softest steel with a (still high!) hardness of 58 HRC. It is most recommended for use with tender cured meats from Italian prosciutto regions such as Parma and San Daniele. It is also exceptional for slicing cooked ham and less cured meats.

    Recommended for: Prosciutto di Parma, Prosciutto di San Daniele, Culatello di Zibello, Spanish Jamón Serrano, and similar.

    Flexibility is necessary
    to some extent, but we have opted for somewhat more rigid flexibility with Burja since this makes it more versatile and suitable for many different types of prosciutto, and at the same time excels when cutting other large pieces of dried meats and other proteins.

    Burja knife is made of Japanese Aichi steel 1K6M VM which will take care of the long edge retention and will be easy to sharpen.

    Burja was fitted a black handle made of pakka wood with a decorative red ring and a stainless bolster for a comfortable grip. Pakka wood is laminated wood, consisting of 70% wood and 30% resin, which makes the handle extremely durable and resistant to humidity, plus it is easy to maintain.

    [Custom handles available!] The handle is an integral part of any knife. With our Burja knife we want to keep things a bit more funky by experimenting with unique, custom-made handles. While the standard version was fitted the black pakka wood handle, custom handles are also available, inspired by designers, artists and woodworkers that we got to know along the way. If you would like your Burja with a unique handle, please contact us at support@sharpedgeshop.com.

    Only one layer of steel is used for the knife to be flexible. When deciding on the steels we wanted to make a knife from, we weigh the characteristics such as hardness, sharpness, ease of maintenance, graininess and ease of sharpening. The biggest challenge was to make the blade flexible enough while keeping the hardness at 58 HRC.

    The slightly concave secondary grind helps the knife to glide smoothly when making longer cuts. The profile of the blade is not completely straight. The slight curvature of the sharp edge reduces the point of contact, which greatly eases the cutting.

    The hammer's imprints, called Tsuchime, were left on the top part of the blade. This keeps the air in the dents, which helps the knife sliding smoothly through prosciutto.

      ☝️ Japanese kitchen knives in our store are handmade from natural materials. Slight variations in color, texture, weight and other dimensions are possible. We try to give a good photographic representation of our products, however computer screen resolution and colors do vary, so products might not look exactly as they are seen on screen.

      Blade wear depends on the quality of steel, usage and maintenance of the blade. Japanese knives are made of high-quality steels. Follow these tips to keep your Japanese knife in top-notch shape:

      ✔ Use a wooden, plastic or rubber cutting board.
      ✔ After use, wash the knives and wipe them dry.
      ✔ For storage, use a knife holder or a protective knife sheath (saya).
      ✔ A good cutting technique is your best bet to prolong sharpness.
      ✔ Use sharpening stones to sharpen the knife.

      ❗️Don’t leave the knife in the sink. Wash it by hand.
      ❗️Don’t wash the knife in the dishwasher.
      ❗️Don’t use the knife on glass, ceramics, marble or steel surfaces.
      ❗️Don’t scrape the food off the cutting board with the edge of the blade. Use the spine of the knife instead.
      ❗️Knife is a tool intended for specific use - cutting food. It is not a can opener, screwdriver, trowel, wire cutter, hammer etc.

      A superb prosciutto requires a precise cutting tool and a certain amount of theatricality in slicing and serving, so a long, thin slicer, resembling a real Japanese katana, is the right choice for the job.

      Based on testing and feedback from professional ham manufacturers and cutters, we eventually developed three completely different Burja knives.


      The Ethos of Burja knife

      The invisible presence of the wind, this great architect of nature who bends mighty trees, invigorates sea waves and creates magical dunes, is also a key component of some of the most distinctive flavors that have accompanied us for millennia. Many times when we look at the beautiful landscapes created by the wind, or at the delicious plates of wind-dried delicacies that melt in your mouth, we are reminded of this humble but undisputed king of natural beauty. Prosciutto makers don't forget to mention their beloved wind - without it, they wouldn't be able to serve their dried delicacies. It is the sharpness of the northeast wind that cuts through the pores of the meat and slowly, with precision, squeezes out the juices and dries the meat until we can call it prosciutto crudo.
      Homo Habilis was the first to use (stone) knives as tools for preparing and sharing food with others. Today, the knife still defines the essence of modern humans, but has changed dramatically since its stone beginnings. The prosciutto knife embodies this ancient essence of a rudimentary knife when we cut a dried piece of meat and share it with friends. 

      Each knife comes with:

      ✔️ Instructions and knife care leaflet.
      ✔️ A preventive Band-Aid – the knives are very sharp! 😉
      ✔️ Original box from the blacksmith, which we wrap in an old Japanese newspaper sheet – so every knife is ready to be passed on as a gift as soon as it hits your doorstep!
      ✔️ We also offer a special gift wrapping option with the traditional Japanese washi paper.
