And I mean any benefits aside from the toughening of the knuckles to condition for contact with hard surfaces.
Well, our bodies evolved through millenia of hardship. They can withstand a whole lot more than we think they can. Getting our minds as "tough" as our bodies--so we don't fold up when the first non-cushioned contact occurs--is something that a makiwara, and similar tools, can help with.
