Hand Engraved

what else could be used to substitute a hand engraver?
i was just wondering what i could use to substitute a hand engraver, simply because I need to engrave initials into a charm for a charm bracelet. please tell me what i could use other than a hand engraver. or a machine! (or do i just use a knife)
Take it to a local jeweler or a watch repairman they can do the engraving for a small cost and it will be a better job then if you did it yourself. Unless you are reallly good at using a hand engraver. If you want something unique you could go to a bead or hobby shop and get gold or silver wire. Cut small pieces and shape the initials and then soder it onto the charm.
