Here's a book by the talented woodcarver, Harley Refsal. He is a master of that lovely Scandinavian style of figure carving that uses a single carving knife and leaves distinctive large flat facets on the carvings. I have DVD in which he is featured and can attest to his skill as a carver.
From the book description:
Directions, front and sideview patterns, and step-by-step photographs reveal how to make a few simple cuts and leave large flat planes intact. The lively personalities of such typical Scandinavian figures as Oskar and a traditional Swedish folk art horse are charmingly rendered in the samples and projects included.
Here is where you can order the book Art & Technique of Scandinavian Style Woodcarving: Step-By-Step Instructions & Patterns for 40 Flat-Plane Carving Projects.
