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:
“Men, my dear, are very queer animals, a mixture of horse- nervousness, ass-stubbornness, and camel-malicewith an angel bobbing about unexpectedly like the apple in the posset, and when they can do exactly as they please, they are very hard to drive.
Oh, England. Sick in head and sick in heart,
Sick in whole and every part,
And yet sicker thou art still
For thinking that thou art not ill.”
—Thomas Henry Anonymous (182595)
“The competent leader of men cares little for the niceties of other peoples characters: he cares mucheverythingfor 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 (18561924)
