Leather working mauls are hitting tools that have a weighted head wrapped in a nylon cylinder. The softness of the nylon makes it suitable for hitting metal leather working tools, such as punches and stamps. Since the nylon is dense, it provides a very solid and effective hitting surface that absorbs shock and delivers a steady hit. Since it is soft, it won’t damage the tools.
Mauls come in different sizes and weights. The heavier mauls will generate more hitting force, though will be a little heavier to hold/swing. It is very much a personal preference as to the weight and style of the maul used.
