Safety gear (safety goggles, heat-resistant gloves, apron, respirator)
Steps:

Preparation: Cleaning the bike gear sprocket to remove rust and debris.
Cutting and Shaping: Using an angle grinder to cut the sprocket and shape it into a sword blank.
Forging the Blade: Heating the sprocket in the forge and hammering it to elongate and shape the sword.
Heat Treatment: Hardening the blade by heating it to a high temperature and quenching it in oil, followed by tempering to reduce brittleness.
Grinding and Polishing: Using a belt sander or files to grind and polish the blade, creating a sharp edge and a smooth finish.
Creating the Handle: Crafting and attaching a handle using wood, leather, or other materials.
Final Assembly: Assembling the sword, ensuring the handle is securely attached and the blade is polished and sharpened.
Safety Tips:
