The number of additional features provided in the design of the knife - in addition to the blade itself, which in this case is not taken into account. We also note that in our catalog this number is not counted by the actual number of tools, but by the number of tool types: for example, three flat screwdrivers of different sizes are counted as one function. See "Features and Features" for details on optional equipment.
Additional functions provided in the design of the knife in addition to the main blade. For multi-tools (see "Type"), in this case, the knife blade is also considered the main tool, and this paragraph lists the rest of the product's capabilities.
—
Can opener. A device popularly known as a "opener" and designed to open cans. It is usually a short and thick blade, hard enough to cut through tin.
—
Knife for cleaning fish. A specialized blade designed primarily for butchering prey while fishing. Note that the capabilities of this blade are usually not limited to cleaning and deboning — in many models it is also equipped with a hook extractor, line guide and other devices for the convenience of the fisherman. This function can be found both in actual fishing knives and in other types of knives (see "Type").
—
Bottle opener. Glass bottle opener with non-threaded metal caps: the cap is pushed on from one side and can be easily removed. Of course, with a certain skill, you can open a bottle even with the simplest knife handle that does not have an opener; however, using a specialized device is both easier and safer.
—
Corkscrew. The classic corkscrew for opening wine bottles is a device in the form of a spiral made of thick metal wire with a sharpened tip. Such a spiral is screwed directly into the co
...rk and makes it easy to remove it.
— Extra blade. Another knife blade, in addition to the main one. Usually, it has smaller dimensions, and may also differ in shape, purpose and type of sharpening (see "Blade type"). For example, the main blade can be made smooth, and the additional blade can be serrated; and in a mushroom knife (see "Type") a curved shape, convenient for cutting mushrooms, can have an additional blade, combined with the main blade of a more traditional shape. Anyway, the second blade makes the knife more versatile; in addition, it can be useful when blunting the main one. Some models with this feature may have more than one additional blade.
— Flashlight. Your own built-in flashlight can come in handy when there is insufficient ambient light, when a full-fledged flashlight is not nearby or it is impossible to use it — for example, during an unexpected power outage in the house or when working in hard-to-reach and dimly lit places. Usually, the light of such a flashlight is directed to the same place where the blade “points”.
— Crosshead screwdriver. Screwdriver for bolts and screws with a cross-shaped slot on the head. It can be either a Phillips screwdriver itself, or a special kind of flat screwdriver, specially designed for cross bolts and screws and differing from classic slotted tools in the shape of a sting. Note that in this case it is precisely the non-removable, built-in screwdriver head (or several heads) that is meant; the possibility of installing interchangeable nozzles (bits) is indicated separately, see "Adapter for a bit" below. So when buying a tool with a Phillips screwdriver, it's ok to clarify the specific dimensions of the sting (stings).
— Slotted screwdriver. Screwdriver with a flat sting and designed for bolts and screws with a straight slot. If necessary, it can also be used with cross heads, however, under heavy loads it can damage the slot, so such work must be carried out carefully. As in the case of the Phillips screwdrivers described above, this function implies a non-removable screwdriver head, the size of which should be specified separately.
— Scissors. In classic knives, the scissors are usually small in size. Due to this, they are not suitable for work involving large volumes or requiring significant effort, however, they can be useful for small household tasks: cut a thread or adhesive tape, cut off part of a paper sheet, cut off a burr on a nail, etc. But among multitools (see "Type"), there is, along with this, another option — when scissors are the main working tool; in some models, they can even be used for cutting metal. Therefore, when buying a multitool with scissors, it is worth clarifying which of the formats it uses — a miniature fixture in the handle or full-sized blades.
— Pilka. The file used in knives usually looks like an additional blade equipped with characteristic teeth instead of the usual cutting edge. Such a tool is unlikely to be useful when harvesting firewood, but it may come in handy for some simple work — cutting small boards (for example, from boxes), sawing off branches of small thickness, etc. Some files can also be used on materials that a conventional blade does not do well: plastic, rubber, thick ropes, etc. There are also tools for metal. Note that serrated sharpening (see "Blade type") is not considered a file.
— Wrench. Separate device for loosening and tightening nuts, bolts with faceted heads, etc. Knife-mounted wrenches are usually fixed sizes — an adjustable design would be too cumbersome. On the other hand, the special shape of the key allows you to work with several sizes of nuts.
— Pliers. Pliers are used to pinch and hold various objects. They are especially useful for those cases when the efforts of the fingers are not enough for this or it is impossible to touch the part with your hands at all (for example, if it is heated to a high temperature). In traditional knives, pliers are quite rare, but in multi-tools (see "Type") are often the main tool. Note that classic pliers with even jaws are almost never used today, usually pliers play their role — a universal tool that combines flat jaws, notches for gripping round parts, side cutters, a wire cutting device, and in some models — also needle nose pliers (see below).
— Nippers. A tool used for cutting (biting) hard materials, primarily metal wire; in addition, it can be used for other purposes, in particular for stripping wires. In modern products (primarily multitools), the so-called side cutters — a type of nippers in which the cutting edges are parallel to the handles. Side cutters are most often not a separate tool, but an integral part of the pliers; see "Pliers" above for details. Also note that some models provide several types of wire cutters — for example, separately for thin and thick wire.
— Pliers. In fact, it is a variation of the pliers described above, equipped with thin, tapered to the ends sponges. Such a tool will be useful for precision work, for which when ordinary pliers are too large, and tweezers do not provide the proper clamping force. Needle-nose pliers are practically never found as a separate device, most often they are made in the form of elongated jaws on regular pliers (for more details, see "Pliers" above).
— Stripper (removal of insulation). Special tool for stripping wires. Its design may be different, but anyway, it was originally designed to cut only the insulation without damaging the metal core. In this way, strippers compare favorably with other tools that are used in electrical work for the same purposes — in particular, from wire cutters.
— File. A traditional file is a tool whose working part looks like a notched surface. In modern knives, files are usually small, finely cut and, like many other full-size tools, are not designed for large-scale and rough work. Such a device can be useful, for example, for deburring or leveling small surfaces. Note that you should not confuse a file with a nail file (see below).
— Tweezers. Tweezers make it easier to work with small details that are difficult to hold in your fingers: its thin jaws allow you to securely hold even very small objects. To further simplify delicate work (in which even a relatively small knife handle can create inconvenience), tweezers are often made removable.
— Awl-sewing machine. The classic awl is a thick needle on the handle, but in knives the design of this tool is somewhat different. Most often, the awl was tetrahedral, somewhat expanding towards the base, vaguely resembling a very narrow and thick blade without sharpening. However, its purpose is no different from the traditional one: piercing holes in dense materials such as cardboard, leather, thin plastic or plywood, etc.
— Adapter for a bit. A device for installing bits — interchangeable working nozzles, which are actually different types of screwdrivers. In fact, the presence of this function turns the knife / multi-tool into a universal screwdriver: bits can have different sizes, be made flat, cross-shaped, tri- or hex, etc. Some models of knives / multi-tools are equipped with their own set of bits and can only work with them; others are compatible with standard screwdriver bits.
— Toothpick. Hygiene device for removing small particles of food stuck between the teeth. Usually it looks like a thin pointed stick and is made removable — picking your teeth while holding a knife handle is not only not very aesthetically pleasing, but simply inconvenient. With regular use, a toothpick should be disinfected periodically — after all, pockets, bags and other places where knives are stored are usually far from sterile.
— Nailfile. Despite the name, this tool is essentially not a file, but a file with a very fine notch, designed for processing nails during a manicure. The use of a file can include both the correction of nails after cutting, and regular filing, eliminating the need to use scissors or tweezers.
— Sling cutter. In modern knives, this term most often means the so-called "safe" sling cutter. It has the appearance of a characteristic hook — folding, removable or built-in (formed by a slot in the handle); with such a device, you can securely grab a sling, rope or belt, and inside the hook there is a sharpened edge, which ensures cutting. Thus, for use it is not necessary to open the main blade, and the probability of cutting oneself is practically reduced to zero. As the name suggests, the main purpose of line cutters is to quickly and safely cut parachute lines (for example, when they are tangled in the air or landing on a tree). In addition, it is convenient to cut seat belts with such a device, which can be a real salvation in an accident.
— Hook. The device in the form of a hook can have a different design and, accordingly, applications. So, in hunting and fishing knives (see "Type") it is made in the form of a characteristic "fang" on the butt of the blade; this fang can come in handy at some stages of butchering prey. In turn, in Swiss models (see ibid.), the hook is one of the folding tools, and here its scope is quite wide: such a device can, for example, tighten a knot, remove a hot pot from a fire, and even make it easier to carry a heavy object , hooking it on a hook and using the knife as a handle.
— Ruler. Your own ruler can be useful for measuring small segments and drawing straight lines — for example, when laying a route on a map or marking blanks for cutting. Folding rulers installed in knives are often made transparent for added convenience. Another option — a ruler in the form of markings on the handle — can be found in multitools.
— Broken glass. Glass breaking device. It usually looks like a small pin on the handle — even a not very strong blow with such a pin is almost guaranteed to break the glass. Rescue work is considered to be the main area of use of glass cullet — in particular, in case of car accidents, when the car door can jam and the window will be the only way out of it. However, there are also less “extreme” applications of this tool — for example, splitting pieces of ice or caked lumps of salt.
— Chisel. A joinery and carpentry tool, which is a rather thick blade, the cutting edge of which is located in the front, in width (and not in length, as in ordinary knives). Such a device is intended for sampling and cleaning recesses in wood, chamfering, etc. It is found mainly in Swiss models and multi-tools. The dimensions of the "knife" chisels are small, they are designed for small volumes of work.
— Magnifying glass. A small magnifying glass that can be used for various purposes. The classic option is to help with looking at small details: miniature objects, small print on maps, drawings, etc. This feature can be especially useful for people with vision problems. In addition, a magnifying glass can be used as a fire source by focus sunlight on a clear day. The term "glass" in this case is conditional, because. in knives, these devices are usually made of transparent plastic — it is not so fragile, and it weighs less.
— Needle (pin). The needle included in the knife tool kit is usually made removable, not folding. Usually, it does not have an eyelet and is not intended for classical sewing, but the length and thickness of such needles often allow them to be used not only for piercing various materials, but also for drawing lines on the surface (scratching).
Note that this is not the whole list of additional equipment found in modern knives and multitools. Manufacturers can equip their products with other devices, such as a crimp for wires, a carabiner for attaching to camping equipment, folding spoons and forks, and even completely exotic features, such as specialized tools for golfers.
