For all those out there that are in the know, can you enlighten me as to why the steel bar is inside heavy bag gloves? I know it's there to protect your hands, but can anyone tell me what it prevents from happening? I've got a pair and my son is starting to hit my bag, but he doesn't like the uncomfortable feeling that the bar gives him. If you look at the illustration, you'll see that the fingers are wrapped around something.
Thanks.
