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.

The SG2 Burja has three big differences that differentiate it from Burja: the steel, the looks, and the handle. Blade geometry and shape and other specifications remain (almost) the same.

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.

    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.

    This Burja is made of SG2/R2 powder steel hardened to around 62-63 HRC, which means it will stay sharp for a very, very long time. The composition and microstructure of the steel provide extremely fine and smooth sharpness.

    The handle attached to the SG2 Burja is universal and easy to maintain. We chose a universal, octagonal shape that comfortably fits the hands of both right- and left-hand users. It offers a firm grip for easy and comfortable use. Handles are made of natural maple wood, which undergoes a special procedure of stabilization with resin. This ensures a long service life of the handle. During this process of stabilization, a color pigment is added which penetrates the wood in different ways, creating unique patterns. This makes every handle one-of-a-kind.
    Color and patterns of handles may vary from what is seen in the pictures. If you like a particular color hue, please contact us before placing an order.

    [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

    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 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. Zero grind edge helps the knife to glide smoothly when making longer cuts.

    This knife features a matte, unpolished finish with a very pronounced line at the bottom of the blade that indicates the border between the two softer, outer layers of steel, and the strong SG2 core steel, seen exposed at the very edge of the blade.

      ☝️ 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.
