Tattoo guns
Back in the late 1800s, Thomas Edison patented a machine called a stencil-pen,
which would engrave words or designs into hard surfaces. A couple years
later, Samuel O’Reilly modified Edison’s invention to insert
ink into the skin – thereby inventing tattoo guns.
Modern tattoo guns have four basic components, including:
• A needle (should be individually-wrapped or sterilized)
• An electric motor
• A foot-pedal, which controls the speed of the needle.
• A tubing system that draws ink into the machine
Tattoo guns can insert a needle into skin up to 5,000 times per minute.
Since each one of those punctures is susceptible to infection, it’s
very important to use a reputable parlor and an artist who holds safety
and sanitation in high regard.
