Blade Knife Blade Sandvik 12C27 Karesuando 75 is made by the Swedish company Karesuandokniven. Knife Blade Karesuando 75 is a classic Finnish knife with a 75mm blade that meets all the standards of puukko style. Karesuandokniven was founded in 1975 in Lapland in the very north of Sweden, on the border with Finland and Norway. There is the village of Karesuando, 250 km north of the Arctic Circle, on the same latitude as central Greenland, and the northernmost regions of Canada. For a person who lives close to nature, a knife is the most important tool that he carries with him in the mountains, in the forest and on the plain. Therefore, the masters of Karesuandokniven skillfully produce knives adapted to nature with the harsh arctic climate of the Arctic. Karesuandokniven knives are created on the basis of centuries-old craft traditions and natural raw materials. Karesuandokniven is known all over the world for its hunting knives, handmade axes in the Lapland style. For more than 45 years of existence of the enterprise, the specialists of Karesuandokniven have produced more than a million different blades. To date, the collection of knives has about 55 different models.
The Knife Blade Sandvik 12C27 Karesuando blade is made from the famous Sandvik 12C27 steel grade. The guide to steels says about it that it is a corrosion-resistant martensitic chromium knife steel of the Swedish company Sandvic AB (Sweden), produced since the 60s of the XX century, which has a low content of impurities - sulfur and phosphorus. In other words, Sandvik 12C27 is perhaps the most balanced knife steel that simultaneously has excellent sharpening characteristics (easy to sharpen - hard to dull, and it really is!), high strength and corrosion resistance. For the curious, the density of Sandvik 12C27 steel is 7.7 g / cm3, and its chemical composition is as follows:
Chemical composition in % (nominal):
Carbon (C) - 0.60%
Chromium (Cr) - 13.5%
Molybdenum (Mo) -
Silicon (Si) = 0.40%
Manganese (Mn) - 0.40%
The unique characteristics of Sandvik 12C27 steel, which allow it to always be at the top of the knife ratings, is simply explained, Sandvik 12C27 is one of the few steels designed specifically for making knives. Most other steels, which have compositions that are much more burdened with master alloys and many times higher cost, are usually developed for other narrower technological tasks that are far from knife topics (for example, for the manufacture of molds or cutting tools with large sharpening angles, etc.). P.). Therefore, for the manufacture of blades, such steels can only be adapted with varying degrees of success.
The production technology of Sandvik 12C27 steel is constantly being improved, which leads to a constant improvement in quality indicators, an increase in density and purity, and an improvement in the fine microstructure of carbides. Therefore, today's Sandvik 12C27 steel is very different from the prototype 45 years ago.
Sandvik 12C27 has high toughness, excellent cutting retention under various mechanical loads and good corrosion resistance. All this makes Sandvik 12C27 the most recommended steel for the production of high-quality top-class knives.
Sandvik 12C27 steel is hardenable from 54 to 61 HRC. However, like most Finnish knives, Sandvik 12C27 blades are hardened to a hardness of 58-59 HRC. The fact is that when operating at low temperatures, in the cold (when the temperature drops, the hardness of steel increases), a blade with high hardness becomes brittle, like glass. Therefore, a value of 58-59 HRC is the optimal value for a knife used outdoors.
