We utilize 2 different edge tuners referenced as ds 7100. Both are pictured below.
The first tuner (Basic) is used in our smaller tune packages and is very functional.
The second tuner (Advanced) shown is a square shaped and comes in many of our more advanced packages. This tuner works for base and side edges.

Works good for edges with a base bevel. Was a little hard to figure out where to put the file (no instructions, no videos I could find). Seems it can only utilize a small portion of the file so I don't know if it will last too long. Still happy I bought it.
