I did it a completely different way than what it is posted here. I heated up some cider vinegar and then soaked a cloth in it. I then wrapped that around the blade and wrapped rubber bands around it to hold it tight. I left it like that for about an hour, then I cleaned the blade off and repeated everything again. Because of the cloth, it ended up having a really cool pattern on the blade. I assume that you can use different texture cloth for different patterns.
