Patent for a new and improved carpenter's hatchet. This design, "by curving or convexing the back of the hatchet downward from the eye to the rear end of the blade [it] greatly facilitates the ease and efficiency with which the hatchet can be used in driving nails in angles and corners—an improvement which will be at once appreciated by all carpenters—while by forming the back of the blade with the opposite recesses, leaving the thin wall between them, the hatchet can be used as a screw-driver, and the carpenter can thus dispense with the use of a separate screw-driver" (lines 67-79).
