These are knock off Mizuno irons. I got scammed and certainly don’t want to do the same to you. There are two 7 iron heads in the set - one of them is very likely a real Mizuno head as I bought it separately. The other is a PW head stamped as a 7 iron. I had it bent to 50° to serve as a gap wedge. The clubs feel super solid and I couldn’t tell a huge difference, if any, between the real 7 iron and the other fakes. But, I cannot tell you if they have the same forging process or the copper underlay. Let me know if you have any questions.
