Hi Pentaxians thanks to all of you responding to my question how-to separate stuck filters, namely Graywolf, Juan, Bob, Amita and more :-)
I followed William Robb's advice using household gloves (common cheap short red ones for Cotty) and it worked very well! It gives you a lot more force and your hands don't slip away from the tiny filter rings. thanks William, you are the hero of the day for me ;-) greetings Markus
