Pros: Effectiveness, Ease of Use, None
Not durable, but effective
When I received the file/stone it had broken in shipping. I'm at an APO, so that wasnt suprising, and it still works. Don't expect this to keep its shape if you're doing anything more than light work on soft metal. I used it to recondition a bolo that had been abused, and when I was finished the ridges were flat. The stone is still very aggressive, so it is not unusable. I would dec omens it to a friend, but with the caveat that it will end up just being a flat file shaped stone.
