The impression I got was that as far as Zerstorer knew, he needed the stick wielded by a Grimm to open the portal so that he could pass through and find his child wife. At least, that's what the Althochdeutsch book in the spice shop seemed to say. Hexenbiests being able to do it as well may have been an unexpected bonus.
