Caleb,
As requested.
A couple of notes;
1. You need a heavy hammer for these, like a 2 lb sledge.
2. Follow the guide lines for stamping in the video I linked to.
3. It works well in end grain but not in long grain.
4. This style, embossed lettering, is generally termed a “makers” mark, whereas the indented lettering is usually an “owners” mark.
Hope this helps.
Craig

@Mexiquite I’m not sure. The text on mine is kind broad, so I don’t think it would work well on steel. Here is the shape ways data sheet on it:
http://www.shapeways.com/rrstatic/material_docs/mds-stainless.pdf

It says it has a rockwell hardness of HRc 20-25. Tool steel is normaly around HRc 50, so I doubt it would work well as a metal punch. It works great on wood though.

I was talking to Paul about putting a mark on metal tools, and he said he would do it with a metal engraver and just carve it on.

After a few years of going to tool swaps, swap meets and estate sales, I have seen mostly engraved marks on metal tools. I have a Disston 23 with a 6″ signature engraved in the plate. I have also seen letters punched in dots – like someone took a punch and made letters with a series of punch marks; Not my first choice for cast iron. If the tool has a wood tote, like a plane or saw, I often see initials simply scratched into the tote. Lastly (and most ghastly), I have seen a fair number of unfortunate tools crudely marked with spray paint for identification.
