Old English hamor "hammer," from Proto-Germanic *hamaraz (cognates: Old Saxon hamur, Middle Dutch, Dutch hamer, Old High German hamar, German Hammer). The Old Norse cognate hamarr meant "stone, crag" (it's common in English place names), and suggests an original sense of the Germanic words as "tool with a stone head," from PIE *akmen "stone, sharp stone used as a tool" (cognates: Old Church Slavonic kamy, Russian kameni "stone"), from root *ak- "sharp" (see acme). Hammer and sickle as an emblem of Soviet communism attested from 1921, symbolizing industrial and agricultural labor.

Hammer is the name of various different fictional characters appearing in American comic books published by Marvel Comics.

Hammer is a 1972 blaxploitation film directed by Bruce Clark. The film was released following the successes of Sweet Sweetback's Baadasssss Song and Shaft, notable 1971 films that popularized black cinema. It starred Fred Williamson as B.J. Hammer. Williamson went on to become a staple of the genre.

The hammer is the term given to the part of a firearm that converts stored up potential energy into the initial source of energy to fire a projectile. It is so called due to the fact that it resembles a workman’s hammer in both form and function; the hammer itself is a metal piece that forcefully rotates about a pivot point. In firearms, the weapon is initially held in a cocked state. When in this state, the hammer has been pulled back and put into a “ready” position with a spring mechanism pulling the hammer so as to cause it to strike when released. This release is connected with the trigger of the weapon, and when the trigger is pulled by the handler of the weapon, the potential energy that is stored in the spring mechanism is released in one quick burst of Kinetic energy.

Once the hammer has been released, it snaps back into its unprimed position and strikes one of various mechanisms to ignite the gunpowder and fire the projectile.

Many firearms in modern times employ a system wherein a hammer comes into contact with a firing pin after it has been released from its primed state by the pull of the trigger. The firing pin acts to linearly transfer the kinetic energy released from the hammer to the primer located in the cartridge itself where chemicals combust, creating a spark, and igniting the gunpowder.

Many modern firearms have the ability by choice of the user or by design to automatically prime the hammer by pulling the trigger. These are often called double action triggers, for they both prime the hammer and release it in the same motion. Other modern weapons still allow the option for the user to manually prime the hammer. In doing so, the user reduces the pull force needed to discharge the weapon, for no additional work must be done to prime the hammer when firing.

The Hammer was an automobile built in Detroit, Michigan by the Hammer Motor Company from 1905-06. The Hammer was a light car built with a two-cylinder, 12 hp engine in 1905. This was replaced with a 24 hp, four-cylinder engine for 1906. The five-seater tonneau weighted 1,800 lbs, and came with a choice of a planetary or sliding-gear transmission, with a shaft final drive. The Hammer Motor Company was formed as part of the Hammer-Sommer when they became defunct in 1905.

A hammer is a type of bullish reversal candlestick pattern, made up of just one candle, found in price charts of financial assets. The candle looks like a hammer, as it has a long lower wick and a short body at the top of the candlestick with little or no upper wick. In order for a candle to be a valid hammer most traders say the lower wick must be two times greater than the size of the body portion of the candle, and the body of the candle must be at the upper end of the trading range.

When you see the hammer form in a downtrend this is a sign of a potential reversal in the market as the long lower wick represents a period of trading where the sellers were initially in control but the buyers were able to reverse that control and drive prices back up to close near the high for the day, thus the short body at the top of the candle.

After seeing this chart pattern form in the market most traders will wait for the next period to open higher than the close of the previous period to confirm that the buyers are actually in control.

Two additional things that traders will look for to place more significance on the pattern are a long lower wick and an increase in volume for the time period that formed the hammer.
