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:
“When you got to the table you couldn’t go right to eating, but you had to wait for the widow to tuck down her head and grumble a little over the victuals, though there warn’t really anything the matter with them. That is, nothing only everything was cooked by itself. In a barrel of odds and ends it is different; things get mixed up, and the juice kind of swaps around, and the things go better.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Our job is now clear. All Americans must be prepared to make, on a 24 hour schedule, every war weapon possible and the war factory line will use men and materials which will bring, the war effort to every man, woman, and child in America. All one hundred thirty million of us will be needed to answer the sunrise stealth of the Sabbath Day Assassins.”
—Lyndon Baines Johnson (1908–1973)
