    While searching for an article in a different post, I stumbled upon an intriguing message regarding a patent dating back to 1879. This patent eliminates the need for voicing using needles or chemicals. The process is remarkably simple: by manipulating core B through screw D and fine-tuning the tension and configuration of the outer layer, the desired outcome is achieved. How simple can it be.

    The information conveyed that the patent was exclusively registered in Germany for a brief period. Regrettably, there is neither a specific patent number nor any reference to the inventor's identity mentioned.
