Good technique is always important. But if you are carving figures or very detailed carvings, you will use far more different techniques than what are in Sundquist's book, and many different tools. If you go to the Woodcarving Illustrated forum, you will rub shoulders with some of the finest caricature carvers in the world. I would say most of them recommend and use gloves. Some of these folks have been carving for over 60 years and their pieces sell for hundreds or thousands of dollars. There is not one technique for carving wood, there are many. When you do very fine carving on very thin pieces, a small unseen blemish in the wood can lead to a serious cut. Cut a tendon and the damage can be permanent. It only takes one serious mistake.
I thought i had made my decision!!!! I think i need to sleep on this one for a while.
