To sharpen a tungsten to a point, which method is commonly used?

Explanation:
Hard, high-melting-point metals like tungsten require an abrasive removal method to shape a sharp tip. Grinding uses an abrasive wheel to carefully remove tiny amounts of material and form a precise point, giving you control over the tip geometry needed for a clean arc. Filing would struggle to cut tungsten and be very slow, while melting would demand extreme heat and wouldn’t give a reliable pointed tip. Polishing smooths surfaces but doesn’t create a point. So grinding is the practical, effective method.
