Saw III (Saw 3) (2006)
axe
Amanda Young:"I'm sorry. I know it's hard to concentrate when you're surrounded by so many things you could kill me with. Like this axe I saw you looking at. Take it. Please, it's yours. Come on. I go for the neck, but I'm not the brain surgeon. Just do it quietly so John doesn't hear me die. Otherwise, he is likely to get upset, rip off his heart rate monitor... boom! Then, you just have to find the sensor and disarm it so you can walk more than thirty feet out that door without the collar detonating. Or you could try and take the collar off yourself, but that could be tricky. The slightest knock in the wrong place could trigger it. I should know. I built it."
