P.S. I don't believe there is such a thing as "Power Whittling".
Whittle \Whit"tle\, v. t. [imp. & p. p. Whittled; p. pr. & vb.
n. Whittling.]
1. To pare or cut off the surface of with a small knife; to
cut or shape, as a piece of wood held in the hand, with a
clasp knife or pocketknife.
At least not according to any definition I know of. Note one of the operating factors, "a piece of wood held in the hand". Chain saw carving and holding the piece of wood being, ahh NOPE.
