This would be a wartime production sword, correct?

Heres a picture of the tip.

Hello, new member here. A good friend of mine's grandfather was a US marine and fought at Saipan. He brought home two swords. Here are pictures of one. We are trying to learn of the sword, its maker, and history. Any help is much appreciated. This website is very informative and interesting. I can tell I will spend a considerable amount of time here reading.
