that's one ugly hand. lol sorry. but it is.

i honestly don't think there is any benefit to roughening up hands like that for boxing, and admit i don't know enuff about martial arts to really judge.

i can understand doing it for martial arts or if you are training for bare nuckle type fighting, but to me if you are boxing and properly you don't need to worry much about hurting your hands if you are throwing properly and well-equipped.

i do use hand grips to strengthen my wrists and hands, but that looks a bit overboard for boxing IMO.
