    KNIFE
    FIELD OF THE INVENTION The invention relates to a knife sheath made for this purpose, which is intended as a tool for equipment when moving in the forest on water or in other demanding conditions. The knife is intended in particular for hunting, fishing and as a tool for wilderness visitors, soldiers, rescue workers or the like.
    BACKGROUND OF THE INVENTION When working in terrain and demanding conditions, the tools are required to have features that allow the tools to function well in all conditions. The knife as a tool is suitable for many different purposes when moving in terrain. At that time, many structural properties are required of a knife to achieve safe and efficient use. The construction materials of the knife must be durable and handled in such a way that, for example, the knife blade is strong enough for loads in different directions. The blade of the knife must be treated in such a way that it can be sharpened sharply and that the sharpening remains as good as possible. Key features are still the structure of the knife handle. The handle should fit well in the hand. The handle should be shaped to prevent your hand from slipping on the blade. The handle should be shaped so that the knife does not rotate or slip in your hand during work. The handle must be suitable for use in different working positions. The knife is carried with the S 25, usually attached to equipment, clothing or a backpack. The structure N of the knife and the sheath must be implemented in such a way that when the knife moves in different positions it is sure that S remains in the sheath, but is easy to implement.
    S z Several different knives and sheaths for transporting them N 30 are known from the past. There are some problems with known knives and sheaths. S In many known knives, the handle of the knife is in principle made in the shape of a cone 2, so that the knife, when pressed into the sheath, is fixed by wedging inside the sheath. > This fastening method may not always work reliably. In addition, the conical attachment requires that the handle of the knife be shaped in such a way that it is not possible to make a shape in the handle which protects the hand from slipping into the area of the blade. Another problem with cone-based attachment is that the attachment is loose and the knife detaches from the sheath, or that the attachment is tight and difficult to remove. In some constructions, the handles have a protective part made for the knife. In these constructions, a separate fastening loop is made in the sheath to ensure that the knife remains in place. The use of a separate loop is also a cumbersome structure. Some plastic handles have a non-slip shoulder, but no fall prevention solutions have been developed for them, so the knife comes off the sheath. US 2019/0009420 A1 discloses a solution for attaching a knife to a sheath.
    However, the structure is complex and cumbersome. In the structure of the knife, no attention was paid in the known solution to the position of the center of gravity of the knife, which should preferably be in the holding grip near the index finger. Ergonomics, which is mainly a shortcoming in known structures, is an essential consideration in the structure and design of the knife handle. US 2019/0176350 A1 discloses kitchen knife handle solutions which may not be suitable for knife use.
    OBJECT OF THE INVENTION The object of the present invention is to provide a knife and a sheath which work together in all situations when moving. The knife is easy to set up and attach to the sheath and the knife does not come off the sheath during operation.
    SUMMARY OF THE INVENTION More specifically, the knife according to the invention is characterized by what is shown in the characterizing part of the protection claims. g 25 S The idea of the invention uses shapes in the structure of the knife handle and sheath that function to enable safe use of E. The knife handle and the sheath are connected to each other by means of N locking shoulders, and the possibility of placing a standard bracket S on either side of the sheath, which is taken into account in the design, is new and inventive. D LIST OF IMAGES
    The invention will now be described in more detail with reference to the accompanying figures: Fig. 1 shows the structure of a knife according to the invention and its sheath in cross-sectional view Fig. 2 shows a side view of a knife structure according to the invention Fig. 3 shows a sheath structure obliquely from the side
    DETAILED DESCRIPTION OF THE INVENTION Figure 1 shows a knife 1 according to the invention, comprising a blade part 2 with a knife blade 3 and an immediately associated rib 4. The knife blade part 2 is made of heat-treated hardening steel, to which a knife blade 3 has been sharpened and hardened. The rib 4 is shaped so that reliefs 5, 6 and 7 are made in the material of the steel part 2 by cutting it into the rib 4. A hole 9 is made in the rib 4 of the blade part 2 for attaching the knife handle 11. At the end of the rib 4 there is a sharp angle 8 heat-treated to cut hard material such as glass. At the end of the bone 4 there is also an opening 10 for fastening loops. The knife comprises a sheath 13 specially made for this purpose. The knife handle 11 is provided with a shoulder shape 12 which fits into a groove 14 made in the sheath 13 so that the knife 1 is attached to the sheath 13. To allow attachment the sheath 13 is made of flexible material and the sheath 13 is made of . (Fig. 3) The structure of the knife 1 shown in Fig. 2 shows shapes N made in the knife handle 11, the purpose of which is to enable an ergonomic grip on the knife handle 11 N 25 during work. The taper16 in the knife handle is made for the placement of the index finger =. The constriction 16 also protects the finger from slipping into the area of the wooden blade 3 7. A roughened shape 17 is made on the upper surface of the knife handle 11 to accommodate the thumb α in the knife handle 11. For other fingers, a roughened gripping point 18 is made on the lower surface S of the knife handle 11. N Figure 3 shows a sheath 13 with a groove 14 made inside the sheath, into which the shoulder shape 12 of the knife handle 11 can be locked. Holes 19 are provided in the sheath 13 for attaching a standard bracket to either side of the body, depending on the hand. Figure 4 shows a knife positioned in the sheath 13 so that the knife is locked by the shoulder shape 12 of the handle in the groove 14 of the knife sheath 13.
    The figures and the related description are intended to illustrate the present invention only. It is clear to the person skilled in the art that similar functions can be implemented by modifying the structure, however, within the scope of the protection requirements of the invention. The functions can be achieved with different material choices for the knife handle or knife sheath, or by using several different materials in the gripping surfaces on the knife handle. O OF O OF O
