First off, WELCOME TO THE FORUMS!!!Grendy wrote:Hunting Knives and Trench Knives are my favorite knife! I've got a lot of collection of this knife! so i advice to collect some of this kind of knife!
Secondly, certain kinda' knives are prohibited by California state law, including certain kinds of "Trench Knives", particularly those with brass knuckles on them.
Unfortunately, California isn't the only state to regulate such knives, even for collectors. I recommend he thoroughly check his State laws as well as any local ordinances before considering such a purchase - otherwise he might be out of a LOT more than the purchase price of the knife should he be caught. It is simply NOT worth it to be in violation of the law.
Hopefully, your location might be more lenient for these kinds of knives, otherwise it simply isn't worth going to prison over some pieces of brass, steel, and iron.
