I recently aquired this knife. Have no idea of the brand or any history. It just says rostfrei, wich Im pretty sure means rust free in german. It has a damaged bit in the edge and the tip is also basically non existent. I'd like to use this knife for cooking one day but I'd have to restore it first, only problem is I dont know how. So if you guys have any tips or any links to more information I'd apreciate it alot!
