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:
“Unquiet wanderer
Draw the Glasnevin coverlet anew
About your head till the dust stops your ear,
The time for you to taste of that salt breath
And listen at the corners has not come;
You had enough of sorrow before death—”
—William Butler Yeats (1865–1939)
“The competent leader of men cares little for the niceties of other peoples’ characters: he cares much—everything—for the exterior uses to which they may be put.... These are men to be moved. How should he move them? He supplies the power; others simply the materials on which that power operates.”
—Woodrow Wilson (1856–1924)
