DH has cut himself on rusty metal. He dropped one of his old and rusty tools on his foot. The cut isn't very big, but i'm not sure how deep it is. I don't think it's too deep, though it has bled quite a bit. I've cleaned it with antiseptic wipes and covered it in antiseptic cream.
He can't remember when he last had a tetnus and neither can I.
Does he need to get one? ( He's not bothered at all, didn't even want me to clean it 
but I am worried!)
