Apparently one of the skis that prince Frisp used on the day of his accident was found abput 2 years ago. The ski/snow manager of Lech shared that he is planning to contact the family when they are coming to Lech this month for their skiing holiday to hand it over to them. If they are not interested, hevplans to destroy it. See article (in Dutch) at NOS:

I personally don't understand why after 2 years this is shared with the media instead of contacting the family shortly after it was found. I assume the family's friend and skiing instructor that they did ask whether this could be Friso's ski will have ways to discuss it with them and otherwisem it shouldn't be too hard either to find a means of communication.
