Idle, your right carvers aren't really idle--even while carving on one their thinking about the next carving.
Welcome, by the way and yes tools are not cheap. Decide what you are interested in learning to carve, then get the appropiate tools for that type.
I like to carve a variety of things so I have both power, wallet and palm tools. As I have been carving for two year my collection has grown.
A good carving knife is a wonderful place to begin, lots of things you can carve with just a knife. Also a carving glove and thumb guard is a good investment. Check with
Little Shavers Wood Carving Supply as you follow the threads on this site other's will be recommended also. For excellent wood and service I recommend
Heinecke Wood Products for basswood and butternut.
Then there is also found wood which makes excellent carvings too.
