Head Materials
Ball-peen hammers have two types of heads: hard-faced and soft-faced. The head of a hard-faced hammer is made of heat treated forged high-carbon steel or alloy steel; it is harder than the face of a claw hammer. The soft-faced hammers are made from brass, lead, tightly wound rawhide, or plastic. These hammers usually have replaceable heads or faces, because they will deform, wear out, or break over time. They are used to prevent damage to a striking surface, and are graded by the weight of the head.

Famous quotes containing the words head and/or materials:
“Thus Satan talking to his neerest Mate
With Head up-lift above the wave, and Eyes
That sparkling blaz’d, his other Parts besides
Prone on the Flood, extended long and large
Lay floating many a rood, in bulk as huge
As whom the Fables name of monstrous size,
Titanian, or Earth-born, that warr’d on Jove,
Briarios or Typhon, whom the Den
By ancient Tarsus held, or that Sea-beast
Leviathan,”
—John Milton (1608–1674)
“Artists, whatever their medium, make selections from the abounding materials of life, and organize these selections into works that are under the control of the artist.... In relation to the inclusiveness and literally endless intricacy of life, art is arbitrary, symbolic and abstracted. That is its value and the source of its own kind of order and coherence.”
—Jane Jacobs (b. 1916)
