Ed, I am super intrigued by this Mezzotint Rocker tool. Thanks for sharing that information. I had never heard of such a tool so I found the Mezzotint Rocker guy (Edward Lyons; Manufacturer of Fine Print Making & Engraving Tools) on-line email@example.com wrote: ..... My daughter has her own shop (brooklynlutherie.com) and she got a tip from the late great Paul Hostetter (lutherie.net for all sorts of great info) and uses a mezzotint rocker for the job. It is a chisel like a toothing blade for a plane and does a great job even on very very old nitro. She uses the 1/2" width

So these mezzotint rockers are spec'd by width and number of lines per inch. The 1/2" one you posted looks to be equivalent to the 45 TPI one (actually lines per inch; LPI) at eclyons.com.
What is best practice for using a rocker to remove the finish at the bridge location ('cause I’m in!)? Bet I’ll be the first one on my block with a mezzotint rocker, “the finest mezzotint rockers available”: ½” X 45 LPI is $43.72 .
Anyone else use one or even heard of it?
