  Hereinafter, various embodiments of the present invention will be described in detail along with the effects and advantages thereof with reference to the accompanying drawings.

It is a figure which shows typically the structure of the side surface side of the kitchen knife which concerns on Embodiment 1 of this invention. It is a front view which expands and schematically shows the structure of the blade line of a blade, the inclination hollow part of a handle part, and an edge part of the knife of FIG. FIG. 2 is a partially enlarged side view schematically showing an example of how to hold the knife of FIG. 1 (table knife method).

(Embodiment 1)
FIG. 1 is a diagram schematically illustrating a configuration of a side surface of a kitchen knife 10 according to the present embodiment. FIG. 2 is a front view schematically showing an enlarged configuration of the blade line 1AL of the blade 1A and the inclined recess portion 2P2 and the end portion 2P3 of the handle portion 2 of the knife 10. FIG. 2 corresponds to a view in which the blade line 1AL of the blade 1A and its peripheral portion are viewed from the direction of the arrow AR shown in FIG.

In the present embodiment, the characteristic points of the knife 10 are i) the configuration of the root portion 2P of the handle portion 2, ii) the material constituting the blade 1A (the blade of the blade 1A), and iii) the blade 1A. There are various points in the configuration of the jaw part 1AAP. Hereinafter, these characteristic points and their advantages will be described sequentially with reference to the drawings.

  As shown in FIG. 1 and FIG. 2, the kitchen knife 10 is roughly divided into 1) a handle portion 2 that is a hand-held portion, and 2) a blade portion 1 having a blade 1A coupled to the handle portion 2. Become. Details of the configuration of the blade portion 1 and the handle portion 2 are as follows.

  First, the blade 1A of the blade portion 1 has a blade line 1AL extending from the blade edge (cut edge) 1AP to the jaw 1AA. Here, as an example, the blade 1A has a single blade except for the jaw portion 1AAP described later. And 1AEP which consists of a part (not shown) (henceforth an "upper corner part") corresponding to the upper corner | angular part facing the jaw 1AA in the base part 1AE of the blade 1A, and its peripheral part. Is fitted into a non-penetrating opening 2P3H formed from the other end side of the end 2P3 of the handle 2 described later to the inside of the handle 2 so that the end 2P3 of the handle 2 is Are combined. Here, the shape / dimension of the portion 1AEP of the root portion 1AE is arbitrary, and the shape / dimension of the through opening 2P3H is determined according to the shape / dimension of the portion 1AEP. For example, when the non-fitting part 1AEP of the root part 1AE has a protruding part (tail part) like the root part of a general knife blade, the protruding part is, for example, the handle part 2 In the case of extending to the convex portion 2P2B, the concave portion 2P2A, or the gripping central portion 2P1, the shape and size of the through opening 2P3H are determined according to the shape and size of the protruding portion. Alternatively, when the non-fitting part 1AEP of the root part 1AE does not have the protruding part (tail part), the non-fitting part 1AEP is, for example, from the end 2P3 of the handle part 2 to the convex part 2P2B. In the case where it exists even in a portion straddling, the shape and size of the through opening 2P3H are determined according to the shape and size of the non-fitting portion 1AEP. As described above, the fitting opening of the through opening 2P3H is provided at the other end side of the end 2P3 of the handle portion 2, and the through opening 2P3H is provided at least in the end 2P3 of the handle 2. .

The first point that should be noted regarding the blade 1A is that the blade of the blade 1A is generally a) less rusting as shown in the enlarged structure of the broken line BL in FIG. 13 chrome stainless steel (hereinafter referred to as “stainless steel”) 4 and a) molybdenum-vanadium steel 5 sandwiched between the stainless steel 4. Here, the molybdenum / vanadium steel 5 is a cutlery steel which is practically used as a material for a surgical knife, for example, and is not easily rusted, and has excellent corrosion resistance and wear resistance and has a sticky characteristic. Therefore, the blade portion 1 or the blade 1A of the kitchen knife 10 is extremely resistant to rust and can provide a very hygienic blade for use. Also, the sharpness of the blade is excellent due to its strong hardness. Has the function of presenting.

The second point to be noted is that the portion surrounded by the solid line SL in FIG. 1, that is, the lower corner portion of the root 1AE of the blade 1A, the lower corner portion forming the jaw 1AA, and the lower corner portion. The jaw part 1AAP composed of the peripheral part (including the part of the blade line 1AL from the jaw 1AA to a predetermined distance d) is not subjected to cutting. In the present embodiment, as an example, the distance d is about several mm. As described above, since the blade portion 1AAP is not bladed, the user of the blade 1A can use the jaw portion 1AAP of the blade 1A to streak food such as meat. In other words, the user of the blade 1 </ b> A can use the single knife 10 to cut the food with various cutting methods (holding methods). This point is very convenient for the user.

  On the other hand, the handle portion 2 includes a) a grip center portion 2P1 extending in the longitudinal direction 2AR from the one end 2E of the same portion 2 toward the blade 1A, and 2) a base of the blade 1A continuously connected to the grip center portion 2P1. And a root portion 2P coupled to the portion 1AE. The handle portion 2 is entirely made of synthetic resin, and in this example, is made of nylon. Among them, a notable component is the structure of the root portion 2P. This point will be described in detail with reference to FIGS. 1 and 2, with particular reference to FIG. 2.

  First, the gripping central portion 2P1 is a main portion that is gripped by the entire palm of the user's hand of the kitchen knife 10, and both sides of the portion 2P1 are drawn with diagonal lines in FIGS. 1 and 2 for convenience. In the same manner, the uneven portions 2P1P are provided as slip stoppers.

  Next, the root portion 2P has an inclined recess 2P2 and an end 2P3.

Of these, the inclined recess 2P2 is waved in an uneven shape that allows the majority of the thumb of the user's hand including the nail portion (excluding the fingertip portion and the base portion of the thumb) to abut when the knife 10 is used. It has a struck shape. That is, the inclined recess 2P2 is continuously connected to the gripping central portion 2P1 and is curved downward in a concave shape toward the root portion 1AE of the blade 1A along the longitudinal direction 2AR of the handle portion 2. A concave portion (valley portion) 2P2A that extends while inclining toward is provided. Furthermore, the inclined recess 2P2 is connected to the recess 2P2A continuously, and extends in a convex manner toward the root 1AE of the blade 1A along the longitudinal direction 2AR. (Yamabe) 2P2B is provided. In the present embodiment, as illustrated in FIG. 2, the inclined depressions 2 </ b> P <b> 2 that corrugate as the above-described uneven shape or valley mountain portion are disposed to face each of both sides of the handle portion 2. Therefore, when the user grasps and holds the handle portion 2 with his / her hand, the user can directly follow the portion near the first joint in the back side portion of the thumb of the hand from directly below the central portion of the nail. The portion corresponding to the above can be brought into contact with the inclined dent portion 2P2 along the curved surfaces of the concave portion 2P2A and the convex portion 2P2B of the one inclined dent portion 2P2. At the same time, the user presses the back side portion of the index finger of the hand from the vicinity of the first joint to the vicinity of the second joint in close contact with the other inclined depression 2P2 located on the opposite side. I can do it. In FIG. 1 and FIG. 2, reference numeral 2BL corresponds to a line schematically showing a boundary portion between the depressed portion of the concave portion 2P2A and the portion where the convex portion 2P2B starts to rise. The reference symbol 2P2BT corresponds to a line schematically showing the top of the convex portion 2P2B.

  The end 2P3 includes a) one end side continuously connected to the inclined depressions 2P2 disposed on both sides, and a) the upper corner of the root 1AE of the blade 1A and the upper corner. It has the other end side part provided with the non-penetration opening part 2P3H in which part 1AEP consisting of a peripheral part is fitted. Accordingly, in the state where the user's thumb and forefinger are pressed against the inclined depressions 2P2 disposed on both sides as described above, the user can remove the above-mentioned nail from the fingertip of the thumb of the hand. The back side portion of the thumb up to just below the substantially central portion can be pressed against the substantially central portion of the end portion 2P3 between the one end side portion and the other end side portion.

  Here, FIG. 3 is a diagram schematically showing an example of how to hold the knife 10 of FIG. 1 by the table knife method as a reference example, and corresponds to a partially enlarged side view of the knife 10. ing. As shown in FIG. 10 and as described above with respect to the above-described configuration of the inclined recess 2P2 and the end 2P3, the user can use the thumb and index finger of the handle portion 2 when using the knife 10. The root portion 2P can be firmly gripped, and the gripping central portion 2P1 of the handle portion 2 can be gripped by the other three fingers, thereby supporting the root portions 1AE and 1AEP of the blade 1A reliably and stably. I can do it. Note that there are other ways of applying the index finger to the root portion 2P. For example, the index finger of the hand is brought into contact with the end 2P3 side of the root portion 2P to support the root portion 2P together with the thumb. It is also possible. In this way, the structure of the handle portion 2 of the kitchen knife 10 naturally guides the user to the ideal holding position when a professional cook holds the kitchen knife when the user cooks the kitchen knife. It has a shape to The user holds the root portion 2P of the handle portion 2 of the kitchen knife 10 with the thumb and forefinger of the hand and holds it firmly, making it easy to make full use of techniques equivalent to professional skills. It becomes possible to cook easily and enjoy cooking.

  Further, the user can hold the knife 10 shown in FIG. 1 by holding the “post method”. Also in this case, the user places the index finger of the hand along the back of the blade 1A and presses the thumb of the hand against the root portion 2P of the handle portion 2 which is an ideal holding position. It is possible to firmly support the root portion 2P of the two, so that cooking by the “post method” can be facilitated.

Also, the user can cook with the knife 10 of FIG. 1 by holding the “full grip method”, which is the way to hold when cutting lines and the like. In this case, the user can firmly hold the grip center portion 2P1 of the handle portion 2 of the kitchen knife 10 as a whole, and reliably perform cutting such as streaking on the food.

(Modification)
The blade used in the kitchen knife according to the present invention may be a double-edged blade or a single-edged blade.

  Further, the inclined recess portion at the base portion of the handle portion may be provided only on one side of the handle portion. In this case, the index finger of the user's hand grips the surface of the substantially flat root portion on the other side of the handle portion. Even in this case, the thumb of the user's hand remains on one side of the handle portion. It is possible to still press the curved inclined dent and the end, and to guide the holding position of the handle portion of the user to the ideal holding position.

  In addition, the non-penetrating opening portion into which the portion composed of the upper corner portion and the peripheral portion of the upper corner portion is fitted is disposed only at the end portion of the root portion of the handle portion. May be.
