Mormuska.

In finnish we call these "mormuska", I'm not sure what is the real name for it in english, maybe ice fishing jig?

But what ever the name is, my uncle makes them!
He has made them for many years and he is famous of them in "fishing circles" at Puolanka and places near. The best ice jigs he keeps in secret, that nobody can beat him at fishing compatitions ;)
He's a real fisher and I love him alot<3
