* Rescaled indices of economic, social and cultural status (ESCS) for use with the PISA 2012, 2015 and 2018 datasets, available in CSV only.
Consider the "Vortex" or "Spiral" cutters in their lineup. Unlike traditional straight-tooth cutters that impact the material with a jarring chop, a spiral cutter engages the material with a gradual, shearing action. The result is a cut so clean it often requires no sanding. For the modern woodworker or fabricator, this is not just a time-saver; it is a preservation of integrity. It means the fibers of the wood are severed, not torn, preserving the grain’s dignity.
