The parts that make up the knife are elements that you need to know and after analyzing in detail the profiles of the blades, types of cod and The most common bisellatures it is important to go to see all the other parts that make up a fixed blade knife and the types of cod.
I did a pattern with nomenclature and variants to try to cover all the possibilities you have in most knives on the market.
This is important for the constructive choice of the knife and to know the different possibilities and offer your customers a wide panorama of choices.
Now I’m going to give you a review of part of the nomenclature but only the main aspects:
The tip of the blade (point or tip), along with the profile of the blade itself, determines the target use of the knife, the design, style and characterization of the shape of the whole knife.
The wire, the tip of the cutting edge, can be flat (plain
edge), serrated (serrated
) or combo (combination of flat wire with serrated blade area).
It can also be present in the end of the blade back, towards the tip, a sharp or false counterwire (swedge, swage, false edge).
The purpose of the counterwire is to reduce the section of the area of the tip, to improve its ability to penetrate, without sacrificing too much thickness at the expense of the fragility of the same tip.
The back or coast (spine or back) is the thickest and most durable part that gives the entire blade support. The thicker or wider the back, use the word you like and the stronger the blade will be throughout its length.
It can be linear or beamed depending on the type of knife, you can insert filework, etc.
The cod is the extension of a portion of the blade that extends inside the handle of the knife and can be made in various ways (below a scheme with the main codoli that you can find on a knife).
The ricasso is the area of the non-biselled blade (where the maximum thickness is thick) from which the codolo (defined later); This form is also the one that influences The fork radius and recollection is placed before the guard (if any) or between the blade and the handle.
The term ricasso was used in the swords to indicate the area after the guard before the beginning of the blade wire which was also used to make advanced two-handed sockets but was then also used in knives where perhaps the term neck would be more suitable in the colts Fixed blade and heel in the lockable ones but the term has been kept without distinguishing the type of knife and in the knife closeable the term tang (cod) is used to define the heel.
The heel (heel) indicates the end of the cutting edge, towards the handle. It is a terminology that was used with kitchen knives where the blade in the end to the handle had a heel-like shape, but today it is a term used in all types of blade sledges to indicate the end of the cuttingedge.
So the ricasso is the flat part of the blade from which the cod is stretched out for each type of knife and the term heel (hell) is the end of the cutting edge.
The term choil indicates the carving after the heel that is needed to get to the limit the sharpening of the knife and that if you want can be formed also to accommodate the index finger of the hand to allow the advanced grip of the knife, in this case it is called finger choil.
The biselli(grind) are the transverse and uniform tapers of the blade that at the meeting of its planes form the cutting edge or directly the wire and the bisellatura is the part that really distinguishes a knife.
Fuller on the blade are grooves whose function is to lighten the blade without sacrificing its resistance but if made in a certain way especially on cutting weapons as large as swords, they did not only have an aesthetic function and weight but also served as a schoolgirl knows to allow the blade to be easily extracted after a lunge.
The handle is often framed by two badges called bolsters that have the function of mechanically strengthening the critical area of the knife between the junction of the blade and the handle but also often as an aesthetic factor being that you can play a lot shapes, colors and materials.
The guard (guard, quillon) or hilt is the fundamental element for the protection of the fingers both from sliding towards the blade during its use and that in combat knives is usually more prone to protect the hand both in attack than in defense.
Generally the guard is positioned across the handle and blade and can be made in the most disparate shapes, from the most essential to the most elaborate with shapes, drawings;
In the traditional form allows the ambidextrous use of the knife but in more extreme knives is done with shapes that allow the specific use of the right or left hand.
These are collectibles or saber screens where a special ergonomics of use and protection of the armed hand is usually required and there are no changes of hand of the weapon itself.
It can be simple with the extension of the back of the blade, with a conformation suitable for the stop of the thumb (thumb rise or thumb ramp), taking advantage of the knife itself appropriately shaped but is often made with an added part grafted as is generally used in hidden cod knives in which the hilt is formed by a central part or solid,from a cruise (which is the central hole, point of the hilt through which the tail passes, and then from the top or bottom branches of the crossbar, or both sides that can have the simplest or most bizarre shapes (straight, curved, symmetrical, asymmetrical, opposites as direction, etc.)
The guard arm is the branch of the hilt that protrudes from the side of the wire, while the parade arm is the one that protrudes from the back of the blade.
Some knives and I’m not talking about the karambit are made with a ring in which to place the index finger (forefinger ring) to have a solid grip of the knife but this technical construction that is seen in some combat knives has many disadvantages because it limits its use by trapping the hand, does not allow the passage in reverse grip and sometimes is uncomfortable if not studied the ring tailored to the person. It also does not allow an easy handover, it does not easily allow the fall of the weapon in case of return of the weapon and anyway you have a finger stuck in a ring that in case of disarmament even if it does not make you lose the weapon is likely to break your finger.
Thehandle can be made in different materials and shapes and can be built with riveted or screwed cheeks, or made for injection molding of synthetic materials, or excavated and planted. It depends on the type of cod chosen and there may be hollows for the placement of the fingers (finger grooves), which improve the grip on the knife.
The glass crusher is a protrusion of the bottom of the handle that comes out and is used in tactical knives to “punch” an attacker/enemy or to break glass in emergency, or other percussive functions. Another name that is used is skull crusher, skull splits.
The lanyard hole nthe end of the handle is often present a , i.e. a piece of lanyard generally used in large knives as a safety measure (placing it around the wrist) but fashionable even in knives closeable to help you pull the instrument out of your pocket.
Now you have a more precise idea of how a seemingly simple object like a knife actually encloses a lot of variants and technical details that can not be overlooked and that go to make the choice of the knife that is often made exclusively to aesthetic level even if it contains many details.
The choice of knife must become more conscious!
