There is a huge number of different options for knives. In fact, manufacturers of leather climb to make something original and not like other products. Also functional at the same time. Here are just all of their creations can be reduced to a few base profiles, on the basis of which the masters are already starting to create. And today we are about these basic blade profiles for knives and talk. Just to be a little better to begin to understand the question.
1. Blade with straight butt
One of the most common models. And not only due to the fact that such profiles much easier to make, but also due to its versatility. Such a knife copes not only with specific tasks, but also perfectly shows itself in everyday practice. It is possible to increase the rounding – it gives a large cutting edge and slightly facilitates further work. Not bad stick, great cuts. Often found in conventional kitchen knives.
In this case, the tip is slightly shifted relative to the line of the butt. The upper cleavage is either even or slightly convex. This increases the efficiency of the thrust, since the point of application of force coincides with the point. The very geometry of the blade facilitates its entry into the material, and pulling back. In addition to stabbing punches and movements, not bad cuts. It is often found in knives designed for self-defense. Butt not usually sharpened.
3. Trailing point
In this case, the point, on the contrary, is raised relative to the butt. This increases the cutting edge, but stabbing becomes extremely difficult. Perfectly cuts soft tissue. Often found in national knives, designed exclusively for processing hides and carcass cutting. Butt can be sharpened, which significantly increases the versatility of the knife with such blade profile.
Also called type bowie, after Colonel Bowie, which is considered the inventor of this profile. The tip is even lower relative to the line of the butt than in drop-point profile. Due to this, the effectiveness of the thrust is further increased, since the point of application of force is practically on the central axis of the blade. The upper bevel is a concave recess, which is sharpened. It can be both short and elongated. This significantly expands the scope of the knife, especially in flaying. Such blade profile It is often observed in combat knives, since it copes equally well with both stabbing and cutting blows. In the second variant, it is possible to use both a blade and a sharpened notch, causing additional damage when pulling out after a thrusting strike.
Quite specific profile. Also called Wharncliffe Blade. It looks like they took the standard version, turned it over, and then sharpened the butt and blunted the blade. Ideal for scraping and provides a perfectly even cut, because the cutting edge is evenly along the entire length of the blade, without any bends. It can be used for making chops. For piercing action is not adapted. Due to the nature of the application, it is rare.
More precisely, “American tantто.” Classic Japanese knives with the same name were straight-butt blades. But in order to simplify production, some craftsmen began to limit themselves to two flat cutting surfaces, instead of one rounded. Due to its shape, it perfectly withstands strong stabbing blows on solid material, without the risk of breaking the point. Provides a good cut, because the cutting surface is uniform. Copes well with chopping blows. Often found in combat knives.
Or spear profile. Ideal for stabbing, provides deep penetration into the fabric and easy pulling. Double edged Most often found in combat, or hunting knives and daggers. Other uses are extremely limited, so this blade profile is relatively rare. However, among the throwing knives, this profile is very popular.
This profile most often used for hunting knives used for skinning. A shorter blade provides greater control over the cut. The upper bevel is not ground to prevent damage to the skin when working. The large bending of the cutting edge provides a more efficient cut, and the point located in the center allows efficient piercing of dense materials.
9. Hawkbill blade
Blade profile, shaped like the key of a bird of prey. The tip is thin, located well below the center line of the knife, providing a sickle-shaped blade. This part is sharpened. This form is extremely inefficient in everyday life and work, but for causing cutting wounds – the very thing. Classic karabits – this is exactly Hawkbill.
Classic stiletto. Narrow, long, double-edged. Very specific application, for domestic and household needs virtually useless. Only for piercing your neighbor.
If in drop point profile on the upper bevel make a small hook, the inside of which is sharpened – we get gat-hook profile, Perfect game cutter. With it, it is very convenient to cut the skins and gut prey. And the rest – the effectiveness of drop point profile. It is better not to use it only for hard stabbing – the hook significantly reduces the strength of the blade when exposed to the center.
These are the main and most common. blade profiles. In addition, there are more narrowly specific options, for example: sheepfoot, dagger point, shark tooth but about all this some time next. Moreover, many simply consider them as varieties of the main options.
