I have had very good luck with the Sculpture House mallet tools that Mountain Woodcarvers have on sale. I would pick up a v tool, a veiner ( a #11 sweep probably a 3-4 mm, and three of four straight shank gouges of different sweeps ( maybe a 3, a 6, and an 8 all in an 6-8 mm). The Sculpture House tools are basic tools and are not as highly finished as Pfeils, but they work well after you get them sharpened up. I wouldn’t worry about picking up any more tools unless you discover you just can’t get by without them. Most carvers end up doing 75% of their work with a relatively small set.
