How to determine if blade has bloodstains??

In my opinion, one does find the occasional blade that does show evidence of blood pitting. Blood pitting is typically deep cratery pits that still have a deep blackish coloration deep in those pits because blood is very corrosive. Take a simple fingerprint. If you do a poor job of wiping off a blade but you leave that one fingerprint check it out in a few weeks. It will be rusting. Just from a fingerprint. If someone just lightly wiped off blood and stored away for awhile it will create deep cratery pits. My friend Philip Tom has polished hundreds of blades over the years, several of which have been ones I owned. He once talked with me about an Arabian Saif of mine that had deep cratery pitting near the tip. He was convinced it was pitting that was the result of blood. He also referenced me to an excellent book which discusses different levels and types of patination on metal but it escapes me at the moment. I will have to dig through my notes and see if I can find the book he had referenced.
