About couple of Items...

[MasaMainio]

So I just completed Amnesia: TDD a couple of days ago, but only one thing was that confused me.

You get the Wooden crank in some point of the game (I can't remember where) and the iron bar from the prison cell (once you get captured by the grunts) if you Take it off.

So my question is, has anyone found a use for these items or are they just for nothing?
