I obsessively write my name on all of my possessions. All my tools, electronic devices, and other possessions. Until my purchase of this engraver, I did all of this with permanent marker, and dealt with the marker getting rubbed off or fading over time. I wanted an engraver, but I assumed that they were expensive because I'd never looked at the prices for them before. I guess the word "engraver" just sounds expensive to me... I don't know.
