I'd like to make a small brand for burning a design into antler and/or bone. This brand will be about 1/3"x1/4". I would like to make it out of iron but I'm at a loss on the best way to cut away the iron to leave a relief of my design. The design is fairly simple and I'm thinking with the size constraints I'll have to use a Dremel but I'm not sure about the bit style to use on steel. Thanks in advance for all replies.

Dremel High-Speed Cutters

Those small thin cutting wheels made out of fibre cut like all get out. They break easy, so safety glasses are required.

You may need several different bits. A needle bit with cutting teeth on it would work to get into the corners and such.
