In particular, it relates to a concave groove type cutting tool structure that reduces cutting resistance and reduces the sticking of food materials by providing a plurality of concave grooves on one side of the blade body, thereby greatly reducing cutting resistance and preventing sticking.
Background Art
[0002] Cutting tools used in the kitchen (such as fruit knives, kitchen knives, etc.) generally have a flat blade body, and various food materials such as fruits, vegetables, and meats are cut at the blade part. However, when using conventional cutting tools to cut food materials, the food materials stick to the blade surface, which not only has an adverse effect on the cutting operation, but also, unless the food materials stuck to the blade surface are removed by hand, the subsequent cutting operation cannot be carried out smoothly.
[0003] In conventional cutting tools, since only the very short end part of the blade body was fixed to the handle, when used for long-term cutting operations, the blade body might come off the handle and fall, and the user might get injured.
[0004] Therefore, in order to surely improve the above-mentioned drawbacks with a new structural form, a technology is required to prevent food materials from sticking to the blade surface of the cutting tool and to prevent the blade body from coming off the handle and falling.

DETAILED DESCRIPTION OF THE INVENTION
[0009] First, refer to FIGS. 1 to 4. As shown in FIGS. 1 to 4, the grooved blade structure that significantly reduces cutting resistance and prevents sticking according to an embodiment of the present invention includes a blade body 10 and a handle portion 40.
[0010] One end of the blade body 10 extends a coupling portion 20, the end portion 101 at the other end is formed in an arc shape, and a blade portion 30 is extended on the bottom edge. A plurality of through holes 21 are formed at intervals on the coupling portion 20. On one side of the blade body 10, a plurality of rectangular grooves 11 arranged at equal intervals are formed horizontally on the blade surface between the top edge and the blade portion 30. An inward concave arc surface 115 is provided vertically inside the rectangular groove 11. Broken wall surfaces 116 are respectively formed on the inward concave arc surface 115 and the left and right peripheral edges 113 and 114 of the rectangular groove 11. The upper and lower peripheral edges 111 and 112 of the rectangular groove 11 are formed in an arc shape.
[0011] The handle portion 40 is coupled to the coupling portion 20 and includes a first handle 401 and a second handle 402 corresponding to each other. The first handle 401 and the second handle 402 are made of wood or plastic material. The first handle 401 and the second handle 402 are respectively fixed to both sides of the coupling portion 20. The first handle 401 and the second handle 402 respectively have fixing through holes 50 corresponding to the respective through holes 21, and a plurality of fixing members 60 are respectively inserted into the respective through holes 21 and the fixing through holes 50. The fixing member 60 has a structure in which a male fixing member 601 and a female fixing member 602 are connected and fixed.
[0012] The blade body 10 gradually narrows from the top edge to the blade portion 30.
[0013] The outer peripheral edge of the joint part 20 aligns with the outer peripheral edge of the handle part 40.
[0014] The blade body 10, the joint part 20, and the blade part 30 are integrally formed by forging.
[0015] As can be seen from the above, the grooved blade structure that significantly reduces the cutting resistance and prevents sticking according to the present invention has the following advantages (1) to (3). (1) When cutting food using the present invention, a large amount of void space is formed between the food and the blade surface by the inner concave arc surface 115 in the square groove 11 and the vertical wall surfaces 116 on the left peripheral edge 113 and the right peripheral edge 114. Therefore, when the blade body 10 contacts the food, the contact area between the food and the blade body 10 decreases, preventing the food from sticking to the blade body 10 and significantly reducing the cutting resistance. Also, since the upper peripheral edge 111 and the lower peripheral edge 112 of the square groove 11 are formed in an arc shape, when cutting the food downward, the food can be smoothly passed through the upper peripheral edge 111 and the lower peripheral edge 112 of the square groove 11. (2) The blade body 10 of the present invention is extended with a joint part 20 extending rearward. Not only is the length of the blade body 10 itself long, but also the first handle 401 and the second handle 402 are connected and fixed, and the outer peripheral edge of the joint part 20 aligns with the outer peripheral edges of the first handle 401 and the second handle 402 of the handle part 40, which means that the lengths of the joint part 20, the first handle 401, and the second handle 402 are the same. Thus, when the user grips the first handle 401 and the second handle 402 of the handle part 40 with the hand, the joint part 20 can also be gripped. Therefore, when performing a cutting operation, it is possible to prevent the blade body 10 from coming off the handle part 40 and falling, and prevent the user from getting injured, enabling safe use. (3) The end portion 101 of the blade body 10 is formed in an arc shape, preventing the user or a person nearby from being cut and enabling safe protection.
