I have removed a couple etchings on PSTs. I used 400 & 600 Roy Emory cloth. Do not work the cloth the length of he handle, as very likely your finish is top edge to bottom edge. Just work your Emory edge to edge by hand. Also, the one of the grits will match the finish on the tool. I did try my rotary tool (dremil) and turns to fast and is very easy to go deeper than desired quickly. Brass wil be much softer than the stainless and can discolor the Stainless unless a compound is used to polish. Slow and steady. Also, I found some company logos are neat, one I removed, I wish I kept😯Ps: Welcome and congratulations on the CRUNCH. BEFORE and AFTER pictures are kind of expected😎
