Every peice of wood is different. One of the biggest parts of being an expert carver is identifying wood that carves well. Eastern maple , red maple , english walnut, black walnut, cherry, all carve very well if you have the right piece. What you need is hard and dence wood. Density can usually be identified by the weight. Dence wood is heavy. To carve well it should be so hard that it will not dent with your fingernail. A peice of wood can be hard at one point and too soft 8" away from there.
For a long time I wondered why Ron Scott , among others,could carve so well. Half of it is , they start out with better wood.
Besides they know what they are doing.
It is entirely possible to do excellent carving and do it the wrong way. It just takes a lot more effort and a lot more time.
