Staple guns may be driven by muscle power, electricity (from domestic power or from batteries) or compressed air. Power staple guns can set staples at a somewhat quicker rate than hand-powered models, but their main advantage is that they can be used continuously for hours with comparatively little fatigue.
Some staple guns have a long nose that allows the staples to be applied into recessed corners. Another special feature may be wire guides for wiring to ensure that the staples will not pierce the wire. The "forward action" staple gun has a handle that points toward the trigger end, in the opposite direction of the traditional staple gun. These tools are easier to squeeze and better place pressure at the front of the tool where the staple is ejected. The first so called "forward action" staple gun was introduced about 1934.
A hammer tacker is a device somewhat similar to a staple gun, except that the mechanical energy from the user's muscles is stored—as with a hammer—as momentum of the gun itself, rather than as compression of an internal spring. This type of stapler is typically used for insulation, roofing and carpeting.
For most purposes square end staples are used; but some staplers can take rounded end staples for holding cables against a surface.
Typical staple leg lengths are 1⁄4″, 5⁄16″, 3⁄8″, 1⁄2″, 17⁄32″, and 9⁄16″, or 6, 8, 10, 12, and 14 millimetres.

Famous quotes containing the word types:
“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
“If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.”
—Henry David Thoreau (1817–1862)
“As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.”
—Saul Bellow (b. 1915)
