TARDIS fairground hammer

From Tardis Wiki, the free Doctor Who reference

The Fifteenth Doctor once pulled a fairground hammer from a compartment in the walk of the TARDIS control room and used it to divide his TARDIS into two. It had a long stripey handle. (TV: The Giggle [+]Loading...["The Giggle (TV story)"])

The hammer was in the Remembered TARDIS, leaning against a shelf on the left side of the control room. (TV: Earthshock [+]Loading...["Earthshock (TotT TV story)"], etc.)
