Jukka cuts the thread off of the spool
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Jukka cuts the thread off of the spool with a knife.
There is no thread remaining on the spool at the end of the task, which means he removed 5,000 metres in total.
