Thanks for the comments guys, no this razor will never hit the BST and will be handed down to my son, I just thought it would be cool for my son to be able to hold something that I not only used but also had tattooed on me when I'm gone.
Inside of the arm doesn't hurt as much as people say, I have both sides of my chest tattooed and I can say that tattooing close to the nipple hurts a he'll of a lot more than the inside of the arm. I will also keep people updated on the rest of the sleve as time goes by!
