Shear tools for lathe work.

[tonyfoale]

I saw the video, and although it is an interesting tool, it wasn't what I expected from its name. "Shearing" is usually used to describe a cutting action, so I was expecting to see something like what a parting tool does. It seems that the process for this tool is more like "burnishing."

Denis,
I didn't invent the name, that is in common use for this type of tool.
The action is far from burnishing, it is a true cutting action, as I am sure that anyone who has used one would testify to.
