And if you don't already know, the pattern says, "Drilling hammer". The short handle with a flared-out end is perfect for working with a cold chisel, star drill, or similar in your other hand. Drilling hammers are nearly always between 1-1/2 and 2-1/2 pounds, and have the symmetric head as shown. Longer handles work fine for stuff like driving a nail, but only because you let go of it after starting - you'd get very uncomfortable if you had to continue holding, as you do with a chisel.
