I you are talking about engraving a name I think any jewellery shop can engrave metal for you, if they can do that on a bracelet or ring they can do it on a blade.
Might check out Mains Enterprises over in Knightstown. There are two guys who run the place, Bill Mains is the namesake and does a lot of hand engraving on guns. Brandon is the other owner and an INGO member. He does some hand engraving and a lot of CNC type engraving. Awesome looking stuff!
N Depth here in Greenfiled also does Laser Engraving. they are located on US40 which is also considered Main here in Greenfield. Also Brandon as mentioned in an earlier post by Clay is a very good choice. He is an INGO member also and is a great guy to boot.
