Ok I have just tested my Hauberk durability to sword and bowie knife, and it is very resilient. No bent rings(from what I could see) and none broke.
Also the mail does come with Back up rings and rivets or pins, about 25.
I stabbed pretty hard with the knife and roughly with the sword.
So Yes I will recommend the mail again. If someone does order from allbeststuff, and things the mail of poor quality that would be a pity.
