The Wrench is an item in Silent Hill 2. It is found on the porch of a house in Lindsey Street in dark South Vale. A map in the director's room of Brookhaven Hospital marks the location of this wrench and a letter. Unlike the later games, the wrench is not used as a weapon.
The wrench is used to open the buried box in Rosewater Park, beneath the statue of Jennifer Carroll. The box is bolted shut and contains an old bronze key, which is needed to enter the Silent Hill Historical Society.
