DETAILED DESCRIPTION OF THE INVENTION

[0020] The aforementioned and other objects, characteristics and advantages of the present invention will become apparent with the detailed description of the preferred embodiments and the illustration of related drawings as follows.

[0021] With reference to FIG. 1 for a schematic view of a knife with laser engraved fishscale lines in accordance with a preferred embodiment of the present invention, the knife comprises a knife body 1 and a knife handle 2, wherein the knife body 1 is a sheet member made of metal or plastic steel such as #304 stainless steel and other material, so that the knife body 1 has a sharp cutting edge 11, a blunt spine 12, and two blade surfaces 13 formed on both sides of the knife body 1, and the knife may be in form of a chef knife, and the knife may be in form of a fish knife, a paring knife, a fruit knife or in other form of knife. The knife handle 2 is integrally formed or coupled with an end of the knife body 1, wherein the knife handle 2 may be a wooden handle, a plastic steel handle, or a plastic handle coupled to an end of the knife body 1, and the knife handle 2 may be made of the same material of the knife body 1 and integrally formed with the knife body 1. It is noteworthy that the blade surface 13 of the knife body 1 of the present invention has fishscale lines 14 which are laser engraved lines the fishscale lines 14, and more specifically the fishscale lines 14 are continuous staggered arc lines, and the size of the arc lines is not limited specifically, so that both surfaces of the knife body 1 have special lines similar to the surfaces of a silver dragon fish or a red dragon fish.

[0022] With reference to FIGS. 1 and 2 for the manufacturing method and structure of the fishscale lines 14, the blade surfaces 13 of the knife body 1 are polished to form mirror surfaces, and then the knife body 1 is placed on a laser engraver 10 and processed by high-energy laser beams to heat the blade surface 13 along a predetermined path, so as to form and the fishscale lines 14 on the blade surfaces 13 of the knife body 1. The fishscale lines 14 formed on the blade surfaces 13 by the laser manufacturing process makes the lattices at the positions of the fishscale lines 14 different from the lattices at other positions of the mirror surfaces, and the laser manufacturing process may be used to form the fishscale lines 14 into indented lines 141 indented into the blade surfaces 13, and the indented lines 141 preferably have a depth L as shown in FIG. 3, and the depth L falls within a range from 0.1 mm to 0.5 mm, so that the fishscale lines 14 have a three-dimensional appearance.

[0023] With the technology of the present invention, the fishscale lines 14 can be formed on the two blade surfaces 13 of the knife body 1 of the knife by a fast, efficient, simple laser engraving process. Compared with the conventional surface etching, die stamping, cutting, grinding or forging processes, the present invention is capable of manufacturing the same blade surfaces with the fishscale lines to achieve the effect of lowering the manufacturing cost. In the present invention, the blade surfaces 13 of the knife body 1 are polished to form mirror surfaces first, and then the fishscale lines 14 are formed on the blade surfaces 13 by the laser engraving process, so that the fishscale lines 14 formed by the laser engraving process are obvious. It is noteworthy that the fishscale lines 14 of the present invention are manufactured by the laser engraving process, so that the lattices at the positions of the lines on the blade surfaces 13 are different from the lattices at other positions of the mirror surfaces. In addition, the fishscale lines 14 may be manufactured into indented lines by the formed by the laser engraving process, so that the structure of the indented lines is capable of separating food from the blade surface 13 or preventing food from sticking the blade surface while cutting the food.

[0024] While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by persons skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
