Blade Skinner 95 12C27

Blade Skinner 95 from Brisa Knives Finland - one of the most famous knife companies from Finland, is made for surface mounting, blade height 30 mm, length - 95 mm, butt thickness 3.5 mm. The total length of the workpiece is 220 mm. Descents are made from the butt. Let us immediately note this very important point. Scandinavian descents, or descents from the butt itself to the supply, significantly improve the cutting properties of the knife, but such a construct is quite laborious to implement, therefore it is inherent only in very good and expensive blades. The workpiece is sharpened, at first glance the knife is very sharp. But this is just a technological sharpening, which indicates the angle that the manufacturer recommends for sharpening this product in the future. Therefore, looking ahead, let's say that after manufacturing the knife should still be sharpened for real. The Brisa Skinner 95 blade is not a classic Finnish puukko, it is distinguished by its Scandinavian descents from the butt and a slightly littered projection of the butt. A slight understatement of the butt line to the tip - something between the blade system, called Normal Blade and Drop-Point, looks very impressive and gives the knife profile both elegance and aggressiveness.
A 125mm long shank allows you to make a handle of almost any reasonable length with through mounting. You can always shorten it if you wish. The shank has a hole with a diameter of 3mm, which can be used for a decorative pin to strengthen the design of the knife.
The blade is laser engraved with the logo of one of the brands under which Brisa knives are produced - Brisa or EnZo and the grade of steel from which it is made - this is the famous 12C27 steel. 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, 12C27 is perhaps the most balanced knife steel, which simultaneously has excellent sharpening characteristics (it is easy to sharpen - hard to dull and it really is!), High strength and resistance to corrosion. For the curious, the density of 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 12C27 steel, which allow it to always be at the top of knife ratings, is simply explained, 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 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, modern steel 12C27 is very different from the prototype 45 years ago.
12C27 has high toughness, excellent cutting retention under various mechanical loads and good corrosion resistance. All this makes 12C27 steel the most recommended for the production of high-quality top-class knives.
Steel 12C27 has the ability to harden in the range from 54 to 61 HRC. However, like most Finnish knives, 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.
