Abstract: A striking tool such as a drywall hatchet for use in the installation of drywall panels in buildings and adapted for driving nails close to the junction of room surfaces, while minimizing damage to the panels, includes a head unit having a hammerhead portion, a medial body portion, and a blade portion. The hammerhead portion has a truncated disk-like configuration, providing a planar top marginal surface, and an arcuate side and bottom marginal surface extending around the hammerhead portion from one end of the top marginal surface to the opposite end thereof, and being convexly curved in the longitudinal direction of the head unit. The hammerhead portion has a convexly curved forwardly facing striking surface extending between the marginal surfaces, including a central milled area and a substantially smooth border completely therearound.
