The Wooden Plank is the first weapon James Sunderland obtains in Silent Hill 2. It is located in the archway at the end of Vachss Road, acquired by James automatically before he confronts the Lying Figure.
It is merely a wooden plank with nails driven through it. It has a limited reach and causes low damage against monsters, making this the weakest weapon in the game. However, the plank is also the only one-handed melee weapon, making it the quickest weapon to swing. It is the most useful weapon and can be relied upon to dispatch most monsters until James can acquire a pipe found located in a car hood near Texxon Gas.
The makeshift weapon and its low damage against monsters also adds to the helplessness experienced in the game's survival horror genre.
Silent Hill: Book of Memories
The wooden plank also exists in Silent Hill: Book of Memories, renamed to "Wood Plank". It is one of the weaker weapons in the game and will break easily.
