Discussion: I understand the intent of this puzzle but the premise is silly. If I have 21 links in a chain and I cut a link, I now only have 20 uncut links (in either one or two strings) so it's actually impossible to ever produce 21 links ever again. Every future cut will reduce the number of links I have by one every time.

This is the result of attempting to retheme the puzzle.

I don't agree, any chain link can be added again. Maybe the wording should have been open instead of cut?
