Do a little searching and you"ll find that tattoos have been applied with a device similar to what you are showing. A look on Wikipedia shows basically the same thing used to mark a D on deserters at one time. Too, "native" tattooing is done using a piece with a "needle" that is dipped in ink and then driven into the skin with another piece that is used as a hammer to strike it. In other words there are ways to get them that are just as, if not more painful, and folks still jump to get them done.
Personally I"ve got a fouled anchor with my rating symbol (a propeller) in the middle of it on my right, upper arm, just below the shoulder. I got it there so it wouldn"t be visible when wearing a shirt sleeve shirt. In reality though I don"t really care if people see it or not, or if they like it or not. The night I got it, I had drawn up designs for several other guys and gone with them for "moral support" to get them put on. We came away from the shop in Naples, Italy with me getting the tattoo, and them all chickening out. Basically it was something I got, for me, as a permanent reminder of something I did that meant a lot to me and was an important part of my life that caused me grow into the man I am today.
Check out the link to read a little about Sailor tattoos. Basically the anchor (in many cases fouled, at least the ones I remember seeing) is for sailors that served in the Atlantic. Taken with the propeller that is the rating bade for a Machinist Mate, and then the letters USN (in red white and blue) under it, it"s something that speaks to 6 unforgettable years of my life where I learned a lot, and got to travel around the world and see more countries, and experience more history, than most normal folks (like me)would/will in their life time.
During the time I spent in I saw a lot of really great tattoos, and a lot of really awful ones. In most all cases they were reminders of people, places, things, etc that had a profound meaning to the guy who got it. True, there were plenty of others that guys got just because. One, for instance, was a guy that has Your name tattooed on his butt. He won many, many free drinks with that tattoo because no matter who he bet that "I"ve got your name tattooed on my butt", he did in fact have "your name" in nice, bold letters. I still haven"t figured out the one that had a bumble bee on the head of a more private area....Now that was way beyond extreme......
