These very deep gouges are formed 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.
This 4-1/2" Ash handle has the same ease of inserting and removing the tool as our other QC handles. Its added length allows for greater power for larger tools. Fits any SK Series tool. TOOL NOT INCLUDED.
