Roger's style of carving utilizes both knives and gouges and power carving tools. Forward roll - a cut which involves only rolling the wrist and closing the hand. Thumb push - a cut produced by pushing on the back of the blade with the thumb. Gouges are used for outlining designs, inserting detail, and taking out large amounts of wood. In general, the scope of the job determines the size of gouge used.
Gouges can be quite complex to sharpen.
In general, the bevels are very acute, concave, and much more shallow than on turning tools. Sharpening can be done with whetstones, power sharpeners, or hones and finished with rouge. Shaping can also be accomplished with rasps and rifflers. Sanding for all the above is best done with cloth backed sanding paper or a burnishing pad. Use this tool with motions like a carving knife for safest and most effective results.
