Description

 The invention relates to a tool used to survive in extreme conditions of solitary existence.

 Known folding knives with a set of spring-loaded blades in the body (US patent N 3825691).

 Such knives include a knife with a set of interchangeable blades in the body and some other elements of survival. Such knives are significant due to the one-sided arrangement of the elements, which leads to their thickening (Appendix to the journal "Internationale Waffen-Magazin". 1990, Brugemann, Switzerland).

 Knives of this type have significant dimensions and weight, 15-20% more than folding knives, the body of which consists of two halves.

 Known folding knives, consisting of two halves of the body (US patent N 4555822). In these knives, the blades are attached and located in both halves of the knife.

 But such knives also have the disadvantages of the above.

 Known folding knives, consisting of two halves with fastening and arrangement of blades separately in each half (Appendix to the journal "Internationale Waffen-Magazin". 1990, Brugemann, Switzerland).

 This knife, although it gives a gain by reducing the size and weight, but has a low functional diversity, which is an important drawback.

 The well-known skadny knife with pliers, adopted as a prototype, consists of two halves (Appendix to the journal "Internationale Waffen-Magazin". 1990, Brugemann, Switzerland). It is used by humans in extreme conditions, including for hunting, protection, household needs, but requires an increase in the thickness and length of the blades. When using the known design in order to survive in extreme conditions, the size and weight of the knife become unacceptable. Also, in the well-known knife there is no necessary set of blades, and their location and design do not provide the possibility of reducing its dimensions.

 The aim of the invention is the expansion of functionality due to the possibility of use for hunting, fishing and the construction of shelters.

 This is achieved by the fact that a folding multifunctional knife containing a case of two articulated halves of pliers, the jaws of which are connected to the halves of the case articulated, spring-loaded blades and screwdrivers mounted on the halves of the case articulated with the possibility of placing them inside the case when folding the knife, and means for sharpening a knife, characterized in that one of the blades is equipped with a harpoon, a saw blade, a razor and a safety protrusion with a protective edge placed on a prototype hinge repleniyu end sharpened blade on its side, with one of the Phillips screwdriver is formed and arranged between two flat screwdrivers.

 In addition, the multifunctional knife contains a tool for sharpening the knife, which is made in the form of a removable file and is mounted on half of the case carrying the blade, while screwdrivers are mounted on the other half of the case, and when folded, the blades and file are placed between one of the jaws of the pliers and the carrier half of the case, the total thickness of the holder of flat screwdrivers does not exceed the diameter of the shank of a Phillips screwdriver, and their length is less than the length of a Phillips screwdriver by the length of its shank.

 In FIG. 1a, b shows the design of a multifunctional folding knife when folded; in FIG. 2 - multifunctional folding knife in working condition.

 Folding multifunctional knife (Fig. 1,2) has two halves 1 and 2 of the body, pliers 3, several blades 4 and springs 5, 20. They are fastened together by hinges 6. The knife is equipped with a harpoon blade 7 containing a saw 8, harpoon 9, a razor 10, a safety protrusion 11 with a protective edge 12. A Phillips screwdriver 13 is located between the blades of a flat screwdriver. The diameter of its shank 14 is equal to the total thickness of the shanks of all three screwdrivers.

 The blade of the main knife is attached to half of the body 1 together with the blade "harpoon" 7 and a removable file 15, and is placed in a folded state inside both halves 1 and 2 of the body between the wall of the body and pliers 3 (Fig. 1, view B).

 The removable file 15 is equipped with a holder with a spring-loaded limiter 16. The knives 17 of the pliers 3 are equipped with locking ledges 18, corresponding cavities 19 on the springs 5.20. The end of the blade "harpoon" 7 in the folded state is located between the pliers 3 and the end spring 5 of the half of the housing 1.

 Preparing the knife for battle and work as a weapon and a tool-instrument is carried out as follows: halves 1 and 2 of the hull are moved apart in different directions, releasing and bringing the pliers 3 into working position. Then, from the half of hull 1, the main blade 4 can be brought into working position , the blade "harpoon" 7 and file 15 by rotating clockwise around the hinge 6. The blade of a flat screwdriver and a Phillips screwdriver 13 are brought into operation by rotating counterclockwise around the hinge 6.

 Breeding half of the hull leads to breeding half of the pliers.

 If necessary, the file can be removed by pressing it towards the hinge 6, when the spring-loaded limiter 16 is activated, the removable file is released and used separately from the knife to sharpen its blades and other purposes, depending on the situation.

 When the blades are brought to the extreme working position parallel to the main axis of the knife, the blades are fixed with protrusions at the base of the blades and the halves of the body.

 The proposed design of the knife allows you to use it to survive in extreme conditions, in addition, in hunting, fishing, in the construction of housing and shelters, repair of equipment and clothing, as well as in the manufacture of auxiliary equipment.

 The design allows you to make a knife in size and weight, satisfying the requirements of the conditions of survival, storage and transportation.
