I want to reiterate what one of the other posters said about sizes of chisels. You need a range of shapes and sizes, not specific shapes or sizes. To start, particularly with carving, you conform the carving/design to the tools you have. You can see how the original makers did this. When you need something specific to implement a design you really want to implement, then you will know what you need and can go buy or make it. I wanted to make this clear, because, in the beginning, I bough exactly what teachers, etc... had on their lists. Frequently, these tools were not used. Follow the advise given by others here to buy a few general sizes and shapes and use those until you realize you need something else. You can always spend money on all sorts of expensive tools and supplies. We have all done it, and we have all wasted a lots of money. If you can make do with what you have, make do. If not, then buy exactly what you need and only what you know you need.
