4 PC #11X THUMBNAIL SET FR920 by Flexcut.
These very deep gouges are designed with a parabolic curve. They are designed to be rolled up to 90 degrees and change shape from deep #11 to a smooth #3 in one continuous cut. The thumbnail grind keeps the corners from digging into the wood as the tool is rolled. Tool length 5".
