I am recently collecting these Sharpfinger. This is a new one I got from Ebay today. As I was cleaning it with rubbing alcohol; the ink smeared all over the scale. Strange! I compare it to my other Schrimshaw, this one is much narrower blade than the others. It has not been sharpened before. On the other side of the tang, it is edged with 0446. Not sure what it is indicated. I hope that this is not a knocked off.
