When a user cuts food using the existing kitchen knife, the edge portion of the metal knife body is easily rubbed against the fingers and the web of the user, resulting in skin damage or calluses. In view of this, the embodiments of the present disclosure provide a knife handle and a kitchen knife, which can reduce or prevent the user's fingers and tiger's mouth from getting calluses or being injured when using the knife.

As shown in fig. 1, is a schematic structural view of some embodiments of a tool shank according to the present disclosure. Referring to fig. 1, in conjunction with a schematic view of the handle portion of the kitchen knife of fig. 5, in some embodiments, the handle includes a handle body 10 and a hand guard 20. The shape and size of the handle body 10 can be designed to match with the palm of the user, for example, a drum-shaped structure in fig. 1 can be adopted, and a plurality of annular grooves (also can be annular bulges or other forms of concave-convex lines) can be arranged on the periphery of the handle body 10 along the axial direction of the handle body to realize the anti-slip effect. The tool shank body 10 may be made of wood, plastic, rubber, ceramic, metal or alloy.

The hand guard 20 is fixedly connected to one end of the handle body 10. The hand guard 20 may be integrally formed with the handle body 10, or may be separately formed and then fixed by welding, bonding, or other fixing means. In fig. 1, the hand guard 20 includes: a blade connecting portion 23, a tiger's mouth protecting portion 21, and a finger protecting portion 22. Referring to fig. 2, the cutter body coupling part 23 is adapted to be fixedly coupled with the cutter body 30. The blade connecting portion 23 may be fixed to the blade 30 by a fixing method such as welding or bonding.

Referring to fig. 5, a tiger's mouth protection portion 21 is located between the blade body connection portion 23 and the handle body 10 for protecting a user's tiger's mouth 41 when the user grips the handle body 10. A finger guard 22 is located between the cutter body attachment portion 23 and the cutter handle body 10 for protecting a user's finger 43 adjacent to one side of the cutter body 30 when the user grips the cutter handle body 10. Finger protection portion 22 can with cutter body connecting portion 23 with tiger's mouth protection portion 21 is integrative to be made, compares in finger protection portion 22 and tiger's mouth protection portion 21 and makes respectively the back mode of fixing on the cutter body of installation respectively again, and the hand protector portion 20 of integrative making is more convenient carrying out the cutter equipment, can improve packaging efficiency.

The material of the hand guard 20 is preferably metal or alloy, so that good rigidity and strength are obtained, and thus deformation or damage of the hand guard is not easily generated when a user cuts food using a knife. The material of the hand guard portion 20 may be the same as that of the cutter body, for example, stainless steel material is used for both the cutter body and the cutter body, which facilitates integral welding, so that the cutter can be made more robust and durable. In other embodiments, the material of the hand guard 20 may be different from the material of the knife body.

In order to improve the pressing and rubbing state when the skin of the tiger's mouth contacts the tiger's mouth guard 21, it is preferable to configure the entire outer contour of the tiger's mouth guard 21 as a continuous smooth surface. Therefore, when the web contacts the web protection part 21, a larger contact area can be formed between the whole outer contour of the web protection part 21 and the web skin, so that the web protection part is comfortable in the pressure feeling of the web and the skin friction of the web, and the local excessive pressure or skin abrasion of the web can not be caused.

Referring to fig. 2 and 4, in some embodiments, the overall outer profile of the first web protection portion 21 is circular arc-shaped in each cross section perpendicular to the extending direction of the blade back 33 of the blade body 30. The shape fully takes care of the knife holding habit of a user, so that the shape of the jaw when the user holds the knife can be matched with the overall outline of the jaw protection part 21, and the jaw when the user uses the knife is protected from being injured to the greatest extent.

In addition, referring to fig. 3, in some embodiments, the first end 21a of the shank body 10 to the second end 21b for connecting the cutter body 30 has a width gradually decreasing in a direction perpendicular to the cutter body 30. The reason is that the shape of the tiger's mouth from the side of the knife handle to the side of the knife body is gradually narrowed from wide to consistent with the width change trend of the tiger's mouth protecting part 21 when a user holds the knife, so that the tiger's mouth protecting part 21 is better fit with the tiger's mouth, and the tiger's mouth of the user is protected to a greater extent.

Referring to fig. 1, 2 and 5, in some embodiments, the finger guard 22 includes: a finger-scratching side protective portion 22a, a finger-gripping side protective portion 22b, and a transition portion 22 c. The finger-scratching-side protective portion 22a protrudes in a direction perpendicular to the extending direction of the handle body 10 with respect to the handle body 10, and is used for protecting the skin of the user's finger 43 on the side adjacent to the cutter body 30 when the user grips the handle body 10. The finger-grip-side protection portion 22b extends out from the handle body 10 in a direction in which the handle body 10 extends toward a side close to the blade body connecting portion 23, and is located on the same side of the thumb-grip-side protection portion 21 as the finger-grip-side protection portion 22a, for protecting the skin of the user on the side close to the blade body 30 when the user grips the handle body 10. And a transition part 22c connected between the finger-scratching side protection part 22a and the finger-grasping side protection part 22 b. Through the design, the fingers can be protected from multiple directions when a user quickly cuts an object.

In order to increase the squeezing force and friction force applied to the fingers when the user grips the handle to cut food, the overall outer contour of the finger guard 22 is preferably configured to have a continuous smooth surface. The overall outer contour of the finger protection part 22 can form a large contact area with the skin of the finger, so that the finger can feel comfortable under pressure and rub against the skin of the finger, and excessive pressure or skin abrasion at the part of the jaw can not be caused.

Referring to fig. 5, in some embodiments, an orthographic projection of the transition portion 22c on a reference plane parallel to the cutter body 30 is in the shape of a circular arc. Therefore, when a user lifts the cutter in the process of cutting food, the fingers can bear the transition part 22c, so that the transition part 22c is arranged to be arc-shaped, the bending state of the fingers is met, the contact area between the fingers and the transition part 22c can be increased, and the fingers are prevented from being pressed too much locally.

Referring to fig. 1 and 2, in some embodiments, among projected outer contours of the hand guard portion 20 that are orthographically projected onto a reference plane (i.e., a plane of paper in fig. 1 and 2) parallel to the cutter body 30, the projected outer contours of the first web guard portion 21 and the second web guard portion 22a, respectively, and the projected outer contour of the cutter body connecting portion 23 are preferably acute angles. The shape of the hand guard portion 20 occupies a smaller space, and the weight of the knife handle can be reduced.

The embodiment of each knife handle can be applied to various cutters, in particular to kitchen cutters. Accordingly, referring to fig. 2, 4 and 5, the present disclosure also provides a kitchen tool including a tool body 30 and any of the foregoing embodiments of tool shanks. The blade body 30 can be fixedly connected to the blade body connecting portion 23 of the tool shank, for example, by welding, so as to obtain a very firm connection.

Referring to fig. 5, in order to prevent the thumb 42 from being worn or scratched, it is preferable that the body connecting portion 23 smoothly contact the surface of the body 32 of the kitchen knife 30, considering that the thumb 42 may be rested on the body 32 side of the knife body when the kitchen knife is used by some users. Accordingly, the cutter body connecting portion 23 may be chamfered or rounded. In addition, the web protection portion 21 preferably has a smooth contact with the blade back 33 of the blade body 30 to prevent the web 41 from being scratched when sliding between the web protection portion 21 and the blade back 33.
