Here are some addresses where you can get sculpting tools. Up to date address over at 1listsculpting or actually on my harddisk since I maintain it.

Feel free to add to it if you know more addresses.
Most of these have wax carvers. Some make specialised tools and in the case of Masquerade miniatures, those tools are designed by a 28mm miniature sculptor.

By the way, I\'ve got a large tool collection because that\'s one of the weaknesses of mechanical engineers: totally toolcrazy. I mostly use the one I mentioned and three rubber tipped clay shapers.
Oh, Tom Meier showed the tools he uses most: a bend edge sharpened needle, a wire bent in a kind of p shape, and a modified x-acto blade.
