Great video posted by our friends at Trent Bosch tools on sharpening your Laurent Niclot Miniature Hollowing Tools.
We use and sell these tools, available in a set of 3/16″ or 1/4″ tools, a straight tool and a bent tool, with or without a handle.
An inexpensive way to get into smaller hollow form turning.
