Fiskars has filed a patent for a method of manufacturing a knife blade. The method involves preparing a blade preform of a first material, depositing a second material that is harder than the first material on the edge of the blade preform through arc welding, and sharpening the deposited second material to create a knife blade with a sharp edge. This innovation aims to improve the durability and cutting performance of knife blades. GlobalData’s report on Fiskars gives a 360-degree view of the company including its patenting strategy.

Method of manufacturing a knife blade with a sharp edge
A recently filed patent (Publication Number: US20230166412A1) describes a method of manufacturing a knife blade with a sharp edge. The method involves preparing a blade preform of a first material and then depositing a second material, which is harder than the first material, on the edge of the preform through arc welding. The deposited second material is then sharpened to create a knife blade with a sharp edge.
The arc welding process described in the patent involves creating an arc between the blade preform and an arc welding tool. The second material is introduced to the edge of the preform in the form of a rod. The rod can be a filled rod, which is filled with powder or granulate. During the arc welding process, shielding gas is fed from an orifice of the arc welding tool towards the blade preform to isolate the location of the welding from the surroundings.
The patent also mentions that the blade preform can be separated from a sheet of the first material during the preparation process. Additionally, the blade preform with the deposited second material may undergo heat treatment before being sharpened. A handle can be attached to a section of the blade preform with the deposited second material, and this attachment can be achieved through injection molding, riveting, welding, or by introducing the section into a slot of the handle to provide attachment by friction.
The patent also describes the resulting knife blade, which consists of a blade section made of the first material and an edge that is arc welded with a layer of the second material. The second material is shaped into a sharp edge and is harder than the first material. The knife blade has opposite first surface sections made of the first material that extend from the back edge towards the sharp edge and approach each other. Opposite second surface sections made of the second material also extend towards the sharp edge and approach each other. The transition from the first surface sections to the second surface sections is provided in the second material, forming an angle between the first and second surface sections on opposite sides of the knife blade. In a cross-section of the knife blade, the first and second surface sections are planar surfaces perpendicular to the longitudinal direction of the blade.
In summary, the patent describes a method of manufacturing a knife blade through arc welding, where a second material is deposited on the edge of a blade preform made of a first material. The resulting knife blade has a sharp edge and consists of a combination of the first and second materials. The patent also details the process of attaching a handle to the blade and provides information on the structure of the resulting knife blade.
