Skew chisels are used primarily for smoothing surfaces (both straight and convex),
but can also be used for trimming end grain, making "V" cuts, turning beads, and other turning tasks.
The skew chisel is one of the basic tools of the turner and much effort is spent mastering its use.
Geometrically it is just a knife held at an angle to the wood, so that is very quickly shaves wood off
to a glass smooth finish. There are tricks to its use - don't let the tip catch or you could
ruin your work. The different designs of the skew chisel are enhancements to help you
work smoothly and safely.
