Item Remembering durability

I’m trying to make a throw able pike. I have just taken the spear and gutted it with pike items. It acts exactly as I thought but when it gets picked back up, it resets the item to max durability. It also has a clip: 1 on it or a 1/# if I have more then one in inventory. I have been around on both issues and have not found a cure.
Any help would be appreciated, I’m working on a tribes mod for a server.
