I was all excited to try these, just got them in the mail. Good thing I only ordered 10, they clearly have a QC problem. So far, I have opened 4 of them and they all have the same uneven grind in the same place. The problem is this crooked run has produced a clearly visible fang below where the bevel is uneven. There is also random chunks missing along the edge along with a wire edge in other spots. Once again, naked eye. I don't have magnification handy. Frankly, this is the kind of quality we were seeing out of Indian Wilkis several years ago, not from Petersburg products. I am going to shave with the forth one, but I am not looking forward to it. I can't fairly judge these based on this box nor can I confidently order 250. So now I have to order another trial amount from another vendor. I am kind of speechless considering the praise heaped on these, does anybody even give a blade a quick glance before putting them in their razor? Maybe I should just stick with Polsilvers.
