I can understand why manufacturers fit cheap three pin plugs with plastic pins on home appliances to keep the costs down. But why do the same with some of my high end tools from Bosch and Festool? They have the same plastic earth pins with live and neutral having metal tips on plastic stems. When you're spending close to a thousand pounds on a tool, having a key operational and safety component made so cheaply is rely frustrating. Today the pin on my Festool battery charger snapped so it was a rummage around to find a spare.
