The rocker said that he was tortured by producer Ross Robinson, who forced him to discuss the meaning of the lyrics he wrote, reports the Daily Star.
"Making the record was sheer f**king hell. It was one of the most difficult things in my life," he explained.
"It was f**king torment. [Ross] put me in a place I didn't want to be. He put me in a horrible depression where I wanted to kill myself again. It was f**ked up. He was just pushing my buttons, tormenting me and f**king me up."
He continued: "He'd find out everything that my lyrics were about, then he'd use that s**t as ammo while I was singing. I got back into a position where I trusted him, but then he abused the s**t out of [that trust] and that killed me.
"He was sticking a knife deep into my heart. It was f**king brutal. He's a motherf**ker. I literally got to the point where I wanted to die. [Bandmates] Fieldy and Munky were worried sick about me. I lost a whole lot of weight, I couldn't eat, I was rotting away."
However, Davis added that the emotional hardships of the record allowed him to quit taking antidepressants and to feel better about his life.
"I feel better than I have in a long time and I think it's because of this album. I've been on Prozac for 12 years and I'm off it now. I know what it feels like to be excited and sad again. I haven't felt like this in 12 years; I'm like a giddy little kid," he said.
Korn III - Remember Who You Are was released on July 13.
