We actually use 2. We use Old one too.
When in Finland, Christmas didn't exist, we still had "tapaninpäivä". Tapaninpäivä still exists, btw. When it was Tapaninpäivä, The nuuttipukki came to hit the nasty children with birch branches. So people nowadays say if you were nasty, nuuttipukki will come.....
WE use both ones at same time, because children are not scared of sticks.
But those are actually birch branches, we just call them sticks.
And nuuttipukki beats you with them.
THAT makes children be kind.
Merry Christmas!
