The cutlery holds very specific terms that can sometimes curb the discovery of this area. You launch yourself in the manufacture of knives and some words are obscure? We offer this scalable list to help you master the entire lexical field of the cutlery and accompany you at best in the manufacture of knives !
HAS
Steel: Metal alloy mainly composed of iron and carbon. In cutlery, the steel serves in particular for the manufacture of blades.
Stainless steel:Iron-based alloy with less than 1.2% carbon and at least 10.5% chromium. Its essential property is to be very sensitive to corrosion. "Food" quality stainless steel must contain at least 13% chromium. (To learn more about French standards in terms of foodness)
Austenic:One of the 4 categories of stainless steel. The austenitic stainless steel is amagnetic, contains chromium (16 to 21%), very little carbon (> 0.1%) and has a high nickel content. This non-soaking stainless steel is very corrosion-resistant, the most famous nuances of this category are 304L and 316L. They are used in cutlery for all appearance parts, not requiring high mechanical characteristics: turntables, miter, false-coins, rods, inserts ...
Austenisation:Action to heat a piece at a defined temperature and duration to solve the carbon and alloys constituting this steel before the quench.
B
Backstand (tape sander or / and touret): Multitasking and versatile grinding system widely used in cutlery. Consisting of a contact wheel and roller trained by an electric motor, the backstand is equipped with an "endless" abrasive band to facilitate your blades and finishing your knives. Fully modular, a backstand can also receive a grinding wheel or surfacing tray on the axis of its motor.
BUSHCRAFT (or WOODCRAFT): "Art of living in the woods", "Art of wood": concept of re-learning life in harmony with the nature and acquisition of more or less old skills to achieve this.
C
Carbon: Latin Carbo which means "coal", carbon is known since the prehistory in the form of soot or charcoal. Element indispensable to earthly life, it is found in nature in its purest forms: graphite and diamond. In metallurgy, carbon is used in making steels by alloy with iron. The higher the carbon content of the steel, the more its hardness will be increased after heat treatment, to the detriment of its ductility.
OF
Damascus: Type of steel obtained by forge welding of at least two types of different metals assembled in successive layers up to several hundred. The metals used have different compositions. The latter reacting differently during the acid revelation phase, they allow to obtain patterns as spectacular than varied.
Damascus titanium :See "TimaScus"
DUCTILITY:Capacity of certain materials (mainly metals) to be stretched and elongated without breaking.
F
Iron: Iron is in different forms of ore in nature. It has been known for several millennia and its remarkable properties make it one of the most used elements in industry. Allied to other components, ferrous or not, it constitutes well-known steel in the world of industry and cutlery.
Forge:The same word to designate the blacksmith's workshop and the metal heating fireplace. Forging, or more commonly "The Forge" is the term designating the deformation action of hot or cold metal by using typing tools (hammer, martinet, hammer-pilon) on a support (anvil or matrix).
BILLION
Guillochage: Essentially aesthetic geometric geometric designs made of the lime or using other tools on the non-cutting parts of the knife (blade, spring, turntable, etc.).
PM
HRC (Rockwell Hardness): Standardized measuring scale to quantify the hardness of a steel such as knife blades. For a blade, depending on the shades and applications the hardness is generally between 54 and 62 HRC
THE
Brass: Non-ferrous or gold-grouped non-ferrous alloy essentially composed of copper and zinc. The proportions of these two constituents are very variable and can enrich themselves, depending on the use to which it is intended, lead, tin, nickel, chromium or magnesium. It would therefore be more just to talk about "brasses" in the plural so its declensions can be diverse and its numerous appellations (Tombac, Florentine or Venetian bronze, the Similar, Archal or Pinchbeck).
Line of quench: Winding or rectilinear line resulting from the quench selective (or differentiated) of the blade of a knife. Also called "Hamon" "in the Japanese tradition of the forge of Sabres, it is revealed by polishing and its aesthetics is very much appreciated in the art cutlery.
METERS
Martensitic: Steel category, one of which is its high carbon content. After heat treatment, it will obtain different mechanical characteristics such as a greater hardness for example. Martensitic stainless steel is one of 4 stainless steel categories. It is magnetic, has high characteristics but minus corrosion that other categories of stainless steel. It is used for the manufacture of knife blades, ice skating, brake discs etc ...
Mokume-Gane:Assembly of different shades of mild metals (brass, brass, gold, silver ...) to obtain - in the manner of a damascus - a decorative metal with various patterns. Used today in jewelry, we also find the mokume on high-end knives for the manufacture of decorative parts.
Mokuti:Neologism resulting from the contraction of the mokume terms and Titanium. (see TimaScus)
NO
Nuance: Variety of metal-based alloy defined by its chemical composition. By extension, the same term can designate steel according to its level of mechanical strength.
O
Outdoor: The term originally used to designate the practice of outdoor aeromodelaminism. By extension, Outdoor relates to all the outdoor activities.
PER
Polishing: Polishing consists of making a smooth surface and beautiful appearance. It can be done manually, mechanically or electrolytic. The quality of polishing aims to obtain a brilliant and scratch free appearance from satin polishing to specular (polished mirror). According to the desired aspect, the choice of steel to use will be preponderant. The EuRotechni team is here to advise you.
Satin polishing:Finishing polishing giving a soft and silky appearance to metal and mitigates the shine.
Poncetage:Game left by the cutler between the blade and the spring when the knife is closed. By leaving a free space, it avoids deteriorating the wire from the blade against the spring at the time of closure
DR
Rank: Each of the stages of the manufacturing process. Some knives may require more than a hundred ranks.
Resilience: Resistance capacity for shocking by shock. Always associated with a given temperature, it is expressed in joules and corresponds to the value of the energy absorbed to break a steel sample
Revelation:Essential step in the creation of Damascus steel knives, the revelation is to immerse the components (blades, handles, platinum, etc.) in an acid bath that will attack and dissolve the steel selectively according to the hardness of the superimposed steel layers by revealing remarkable and very elaborate inchlecks. The treatment ends with a last bath of a solution that will definitely neutralize the effects of the acid.
Income: The process of quench is done in several stages: austenitization, cooling (commonly called quench) Then income. This indispensable phase of heat treatment can be carried out at different temperature levels, it has therefore dropping the hardness of matter but improves the ductility by ending its structure. For strongly allied steels, it may be necessary to achieve several income. The choice of income temperature is based on the disclose ductility / hardness / corrosion resistance that we are looking for.
S
Specular (polishing): Is said of a mineral or metal that reflects light like a mirror. Otherwise designated by "mirror polished", it is extremely meticulous polishing that removes the scratches and imperfections of the metal by giving it a maximum brilliant.
Removal Stock:The manufacture of a knife necessarily begins with the shaping of the metal parts, and in particular the blade. This can be done by the technique of the forge, or much more easily especially for beginners who do not have the necessary equipment, by removal removal ("remedal stock" in English) which consists in using flat steel bars with the approachable dimensions of the room to create. The blank work will then be done by mechanical methods of metal removal (lime, grinding wheel, abrasive band ...). Eurotechni has a wide selection of profiles and nuances of specific steels in stock removal.
DOES
Tenacity: Ability of a material to withstand the spread of a crack
Timascus (or Mokuti or Damascus titanium):Anglophone term, contraction of Titanium Damascus (Damascus of Titanium in French) Like Damascus, Timascus is an assembly of at least two shades of Titanium (Grade 2 and Grade 5 most often) in many layers. After different operations, folding, cutting, stamping, we get a metal with various patterns and colors for the manufacture of handles, inserts, clips or mitters.
Thermal treatment:Process performed in several steps to give steel the desired characteristics. The choice of steel is essential to obtain a perfect heat treatment according to the future use of your knives. EuRotechni can help you in these choices.
Quench :The quench is the cooling step after austenitization. After heating and maintaining steel at a certain temperature, it is cooled in a specific medium (air, oil, water etc ...) to freeze the structure of the material and to change its mechanical characteristics. By abuse of language, the term quench move more generally reference to the two combined steps (austeanization and cooling). For each of the Eurotechni steels, a specific technical sheet in detail the phases of quench and income that will allow you to get HRC hardness you want to give to your blades.
Quench selective:Method of quench to obtain two levels of steel hardness on the same blade. The purpose of this type of quench aims to obtain a blade combining a certain flexibility on the back for more resistance to the stresses and a high hardness of the cutting edge for more performance. After meticulous polishing, a blade elaborated by quench selective can be revealed to let appear a "line of quench"Very aesthetic forms particularly appreciated on Japanese saber blades.
Kit:Name given to stacking steel platelets for the realization of a Damascus steel. The platelets are assembled by welding and equipped with a handle to facilitate the handling. The search for patterns for the future Damascus steel is done at this step by calculating or randomly by selecting the number of starting pads and the order of their stack.
