Just the thing for aiding the break-in process without softening those parts of the glove you DON'T want soft (as steaming does).
Used it to break in a new Rawlings Pro-Preferred 1B mitt... not an easy thing to do. But, using this mallet has the glove game ready in days instead of weeks.
Pros: Feels good in the hand
Heavy enough to have real impact
Bottom Line: I would recommend to a friend
