Hello I'm starting in the world of knives collection so even if I started to read forums, watch videos and stuff to learn general things of course I'm still a ignorant on the matter ... My preferences are antique knives, mostly military knives and bayonets and any antique with a strong and good quality blade. One thing and the first one to call me the attention when I started and is what I want to ask to anyone who can tell me something about it is that I imagined that in this knives collection world the name of brands and models were totally essential to identify a knife for who is disposed to invest his money on buying one. Especially if they are military and antique or just antique knives with a big history behind. Just like for example car lovers world,musical instruments world, guns world (or almost any articles world) where knowing the brand and models are essential especially to know the year and place of fabrication and know something else about the piece. But I realized that is very common to find antique knives with no brand or model ID, and even if it has it sometimes is quite erased to read it or just name the brand and not the model and when you try to look information on internet about where and when that knife could be made it's impossible because maybe you know the brand, you know it's a german brand for example but there is not much information about the model. Why is that? It isn't for a knives collector very important to know as much as they can about a piece? I hope my question gets understood. Thanks!
