Elmax Steel Scandi Brother knife
This knife is hand forged out of a piece of Swedish Elmax powder metallurgy steel.
Uddeholm Elmax is a high chromium, vanadium- molybdenum - alloyed third generation powder metallurgy steel with high wear resistance, high compressive strength, corrosion resistance and very good dimensional stability. High wear resistance is normally connected to low corrosion resistance and vice versa. In Uddeholm Elmax SuperClean it has however been able to achieve this unique combination of properties by a powder-metallurgy-based production. Elmax Steel chemical compounds are as follows: Carbon 1.7%, Silicon 0.8%, Manganese 0.3%, Chromium 18.0%, Molybdenum 1.0%, Vanadium 3.0%.
Although high wear and corrosion resistance are typically hard to find together in a knife blade, this steel’s powder-metallurgy based production allows for its imperviousness to wear (sideways shifting of the metal from its original position), and corrosion (gradual destruction of metals). ELMAX is produced through a hardening and corrosion resistant mold using this powder-metallurgy process, a process that Bohler-Uddenholm uses for many of their premium stainless steels. Powder metallurgy is the method of blending fine powdered materials, pressing them into the desired shape, and then heating it to sinter, or bond, the material.
This gives the knife the desired traits of superior edge retention and an ease of sharpening, which is often the reason that people are attracted to such stainless steel knives. The steel’s “Superclean” production process combined with small sized powder and carbides guarantee trouble-free grinding and polishing.
As opposed to most other steels, ELMAX is simply more convenient, as well as more all-around than other knife steels. Throughout numbers of tests, there were simply no flaws to be found. Other knives are prone to certain flaws and weaknesses, and where they might be strong in one aspect, they lack in another. Many knives are tough but hard to sharpen. Many are sharp, but prone to corrosion and rust. Others do not rust easily but make softer blades. With ELMAX, you get receive little or no such setbacks, as well as all around quality features.
After the grinding is done, the knife is heated in a computer controlled oven to precisely 1080°C (1976°F) and then quenched in a circulated air quench. To reach the 61 HRC hardness for the blade it is subzero treated for 2 hours at -80°C (-112°F) in dry ice. This is also called cryogenic hardening or deep cooling. The super cool temperatures transform the steel structure from austenite into martensite. Cryogenic hardening relieves some stress, raises the Rockwell hardness by 1-3 points and refines the internal grain structure of the steel. The knife is then annealed for 2 hours in a tempering oven of 220°C (428°F).
The blade for this knife is matted using a very smooth sand blast stream. The sand for this final abrasive is taken out of our local river-bed. Afterwards, the blade is smoothly polished with diamond polishing paste, giving the blade a satin finish. Afterwards the knife is honed to razor sharpness.
The handle for this knife is hand shaped out of a block of stabilized curly Birch, thermally treated wood that grows very slowly in the far North in Finland (Lapland). It is oiled with a pure tung nut oil and afterwards waxed with beeswax.
Leather sheath is wet formed to fit each knife individually. The leather material is manufactured in a local tannery using the same methods and techniques that were used 100 years ago. Each sheath is custom made and hand stitched using saddle stitch and waxed linen thread. Each knife sheath is individually custom dyed with Fiebings professional oil dyes. Afterwards, the sheath is waxed with palm leaf wax and beeswax. To protect against moisture it is finished using acrylic leather sheen.
