"Tool to use on metal and wires. Rusted, but usable."
To obtain the Key of Ophiel, which is stuck in a shower room faucet.

The Pliers are an obtainable item in Silent Hill. Harry Mason comes across a pair of them in a room connected to the classroom in Nowhere. Rusted and old, they serve no less than an important tool, allowing him to remove the Key of Ophiel from the bathroom faucet, in which it is lodged.
