The patent application (Publication Number: US20240035290A1) describes a method for constructing a metal hand tool with a blade piece and a contoured handle. The method involves aligning and welding symmetrical handle half pieces to form the contoured handle, leaving the distal end open to receive the elongated tang of the blade piece. The blade piece is then welded to the contoured handle, creating a convexly curved connection that stiffens the blade relative to the handle. Additional steps include inserting an open hang hole piece and welding it to the handle, as well as welding a metal tang guide piece for further reinforcement.

Furthermore, the method includes spot welding the handle half pieces at specific positions, inserting the elongated tang through the handle, and welding the blade piece to the contoured handle to form a convexly curved connection for added strength. The process also involves inserting an open hang hole piece and welding it to the handle for additional functionality. By following this method, a durable and sturdy metal hand tool, typically made of stainless steel, is constructed with a contoured handle and a reinforced blade piece, suitable for various applications. The detailed steps outlined in the patent application ensure a precise and effective construction process for producing high-quality metal hand tools.
