The Ice Pick isn't used anywhere in the story and can't be obtained by normal means. It is hidden in Divided They Fall and can be accessed with the debug menu.
The Ice Pick is still left in the files for Manhunt 2.
- Hasty: Cash taps on the hunter's left shoulder, as the hunter turns around he then plants the ice pick into his face. Cash then puts his hand on the hunter's left shoulder and wiggles the ice pick out as the hunter falls to the ground.
- Violent: Cash chops the hunter on the right shoulder, causing him to fall to his knees. Cash then chops the back of the hunter's head as he falls to the ground.
- Gruesome: Cash swings the ice pick into the hunter's lower spine, he then slices the ice pick up the hunter's back as he falls to the ground.
