A farmer in Nebraska saved his own life by cutting off his leg with a pen knife as he was being sucked into a piece of machinery.
Kurt Kaser, 63, was transferring corn from one bin to another when his left foot got stuck in the equipment
As his leg was being pulled in and mangled he took his 7.5cm pen knife out and sawed off the limb below the knee.
After freeing himself he crawled 60m to the nearest telephone and was flown to a hospital.
Kaser, a corn, soybean and pig farmer, said he never lost consciousness during his ordeal, which happened on April 19.
He told the Omaha World-Herald: "I didn't know what to do. I was afraid it was going to suck me in more. I about gave up and let it do what it was going to do.
"It's hard to describe. You want to survive and you do what you need to do to survive, I guess."
Kaser said he cut through up to 2.5cm of muscle and nerves below his knee to free himself.
He added: "The bone stuck out down to my ankle. That's what I was hanging onto as I was trying to get myself out."
The farmer had become trapped in an auger, a tube that uses a rotating shaft to suck grain.
He did not have his phone and there was no one around to help.
Kaser was later released from a rehabilitation centre and will have to wait for the amputated leg to fully heal before he is fitted with a prosthetic leg.
He said: "I was in a hurry and didn't pay attention. Farmers, we're all guilty of it but we don't stop and think. We get in too big a hurry.
"Everybody says 'You seem so upbeat about it'. I know I will be walking again fairly normally. Other people can't, won't ever."
