Made this as a Christmas present.
It is all stainless steel so it is food-safe, and will not rust.

The texas shape was cut from a $5 spoon rest I bought from a department store. I could not find a pice of stainless steel anywhere locally, and the spoon rest was cheaper than ordering a piece online.

I downloaded the texas image from the internet, printed it and used spray-adhesive and tape to attach it to the steel. The plan was to cut it out with a scrollsaw, but it wasn't powerful enough, so I just the VERY basic shape on the bandsaw, then ground down to the lines with a bench grinder. 

I ordered the 3/8" SS rod from McMasterCarr and had it welded at a local welding/fab shop. They didn't charge me anything because it was such a small job!

I used my cheap Harbor Freight tap&die set to thread the rod, and used an old handle from a wood-file for the handle. I sanded the old paint off, stained it, and put on 3 coats of polyurethane and 2 coats of wax.

I used PhotoShop to get the letters and star, then reversed the image, printed it. I put a layer of packaging tape over the texas shape making sure there were no bubbles, then taped on the pattern I printed out. I then carefully used an exacto-knife to cut out the star and initials. This left only the initials and star revealed and everything else covered with packaging tape.

I electro-chemically etched the pattern. This is a real simple process. I used a 12v 10A battery charger (there was also a 1A setting that worked just fine, but the 10A was faster). I clipped the positive terminal to the SS rod, and the negative clip to a Q-Tip that had been dipped in a salt-water solution (just stir salt into the water until the water will not hold any more salt in suspension). I just dipped the tip of the Q-Tip in, and made sure the neg. terminal clipped onto some of the wet cotton. Then you rub the Q-Tip across the exposed metal that you want to etch. The Q-Tip will turn black fairly quickly, so change then when necessary. 
Be CAREFUL when doing this, do NOT inhale the fumes, and do NOT let the neg. battery terminal contact the metal directly. 

When I was happy with the depth of etching, I pulled all the tape off, and polished the whole thing using the buffing wheel on my dremel.

This is a fun project, but BE CARFUL, it does involve some potentially dangerous tools/processes, if you are not comfortable with these tools/processes, do not attempt.

My former employer purchased an etcher to do that for ~$1000.00. It took 45 minutes just to mark S.Steel to read the image. Very Cool.

Nice etch job. About how long did it take to etch, and roughly how deep would you say it is?

I dont know exactly, I'd say the etching is about as thick as cardstock. Apparently you can go all the way through if you are patient enough. It took about a minute per shape to get that depth.

No kidding. That's really quick. I may have to try that on some copper I have laying around for an enameling project. I have a brush plating wand that would probably work instead of the q-tip, too. Thanks for the inspiration!

I think we might smoke some ribs or brisket this week, so I will post an action shot once I have it!

I agree with lemonie.  I want to see this baby in action.

amazing job. I've never heard of that electrolysis technique, thanks!

This isn't complete until we see what is does... - can you add a picture of something branded?
