Hello, I have a set of knives that my dad left me. They have the marking"Trident Dreizack Solingen Germany Rostfrei" along with a product code and size. On the handle there is an engraved trident symbol. I have no idea as to the origin of these knives but would really like to know what they are. I have researched Wusthof as they have the same trident logo but don't know whether these are the same brand or not. I have put some pictures below. If anyone can help I would be very grateful. Thanks.
