The knife the prosecution contended had inflicted the distinctive injuries to Wolfe's forehead was introduced in evidence as Exhibit 4, with Corporal Thomas Harding testifying as to his handing this weapon to Sangret on 26 August. In response to questioning by his defence, Sangret denied he had ever seen the knife introduced into evidence, and claimed he had never being given such a weapon by Corporal Harding. Furthermore, Sangret described the knife he had used to construct both wigwams as belonging to Wolfe. This weapon, he claimed, had both a marlin spike and a can opener, and he had been informed by Wolfe that the knife had been given to her by Francis Hearn. In addition, Sangret insisted he had never taken his own army-issue knife off barracks.
