Dual-wielding S&C cutter

Abstract

This product provides a cutter that can perform two types of tasks with a single tool, eliminating wasted time such as switching between cutters or searching for tools. [Solution] A dual-blade S&C cutter with a straight blade on one end and a uniquely developed curved blade on the other, with plenty of replacement blades available that can be broken off when worn out. The backs of two cutter knives are fixed together back-to-back to form a single sheath body. One end of the sheath body is fitted with a conventional straight blade S, and the other with a curved blade C, allowing you to select and use the blade while holding it. A saw blade can also be attached as needed. The tip of the sheath body is curved so that the blade tip can be guided in and out of the sheath body without resistance.

Description

【Technical Field】 【0001】 The present invention is a tool in which the sheath bodies of two identical cutters are fixed back to back and equipped with two types of cutters integrated together. 【Background Art】 【0002】 In conventional work that requires a cutter, it is common sense to attach a single straight blade to one cutter sheath body. For different working processes, switch to a different tool for work. Currently, the situation is that people continue to work by picking up a tool that can be used without any dissatisfaction and without cumbersome operations. 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 In work using multiple cutters, the present invention considered whether two types of work could be done with one cutter without wasting time such as replacement time and the time to search for tools. If the back parts of two cutters are fixed back to back, two types of blades that can be used as they are can be reversed and selected within the hand, and by operating the slider, the necessary blade can be used, thinking that wasteful work and wasteful time can be shortened and improved. The present invention invented a two - blade - flow S&C cutter by attaching an existing straight blade that is commonly used in all kinds of work, which can be folded and used when it is worn out and has a rich supply of replacement blades, to one side, and attaching a curve blade developed independently to the other side. If necessary, a straight blade and a saw can also be attached to both sheath bodies. The present invention was invented to solve these problems. 【Means for Solving the Problems】 【0005】 This invention is a dual-blade S&C cutter that uses two sheaths fixed back-to-back, with one sheath fitted with a (S) straight blade and the other with a (C) curved blade. The straight blade can be fitted to either sheath. It is an extremely simple cutter with features that eliminate the need to switch hands, allowing you to select the blade to use by flipping it in your hand with one hand and instantly extending and retracting the blade by operating a slider with your thumb. In particular, (C) curved blades are curved blades made by shaping spring steel into a curved form and then sharpening it. This is a dual-bladed S&C cutter with the features described above. [Effects of the Invention] 【0006】 The dual-bladed S&C tool has a good reputation, and the blades can be changed while holding it. The (C) curved blade, in particular, has received positive feedback during the prototyping stage for tasks such as hollowing out fruit, harvesting from home gardens, woodworking, chamfering, carving, and cutting packing string. [Brief explanation of the drawing] 【0007】 [Figure 1] These are the rear view, top view, and front view of the existing product.

[Figure 5] This is a diagram showing the X-shaped area in the upper right oblique view of the present invention, with both blades exposed. [Figure 6] This is an enlarged view of circle X in the upper right perspective, showing the double-edged blades of the present invention. [Figure 7] This is a perspective view of the present invention from the upper right. Embodiments for carrying out the present invention 【0008】 (a) Drawings 1 and 2 show the rear view, top view, and front view of an existing cutter knife. (i) Figure 3 shows a single sheath body in which two cutter knives are fixed back to back and integrated in the present invention. (c) Drawing 3 is an integrated plan view, front view, and front view with the blade extended. (e) Existing products will be described as having straight blades (S) and curved blades (C). (O) It is an integrated type equipped with two types of blades: an existing S-blade attached to one sheath and a C-blade attached to the other. (Holding the integrated sheath body, you can instantly extend or retract the blade by selecting one blade and operating the two sliders back and forth with your thumb.) (K) Drawing 7 shows that the curved cutter is made by first shaping spring steel into a straight blade shape, then machining the blade mounting holes, and finally shaping it into a curved shape to complete the product. (k) Drawings 5 ​​and 6 show that the tip of the sheath is curved so that the blade tip can be guided without resistance when inserting or removing C from the sheath. The present invention has the configuration described above. When using the present invention, When using the dual-blade S&C cutter of this invention, which incorporates two different types of blades, hold the sheath and body, select either the left S-blade or the right C-blade, and push the slider forward with your thumb to extend the blade to the appropriate length before use.

Claims

[Claim 1] Two cutter bodies are fixed together in parallel, back-to-back, and the backs of the two bodies are fixed in parallel, creating a single integrated cutter body equipped with two types of blades in parallel. [Claim 2] The sheath body has a 7X curved section on the side where the C-curve cutter is attached, allowing the tip of the sheath body to be guided without resistance. [Claim 3] A two-bladed C-curve cutter made from spring steel that has been shaped into a curved form, then sharpened, heat-treated, and polished to finish.
