NM-2 mallets are manufactured from high impact nylon with a hickory wooden handle for extreme durability and are specifically designed for roughing in your work during the early stages of metal shaping and typically used in conjunction with a shot bag. Made from a nearly indestructible non-marking material, these mallets have flat ends for added usefulness and practicality

SDS-5, SDL-2, TPD-3 & CD-3 T-dollies are used to form flanges and edges by hammering the metal with a hammer or slapper over the rounded part of the dolly. These dollies are smoothly finished to prevent damaging the material you are forming.

They're the same specialty straight T-dollies auto body shops and fabricators use to form and shape sheetmetal flanges and edges.
