This thread on planetFigure might be some inspiration, you\'ll see most of my wooden tools made as per Orb\'s comment above:

You can make some of your own sculpting tools from old brush handles, wooden dowel, cocktail sticks/toothpicks, needles, plastic cocktail stirrers, brass or bronze rod, coathanger wire, nails, hypodermic needles, hardened putty... you\'re only limited by your imagination and drive. Sometimes there\'s nothing better than making a tool specifically for a certain job and having it work just right
Just wanted to mention also, all of the commercial sculpting tools in my photos were improved so if you see one going cheap somewhere and it\'s a little crude don\'t necessarily be put off. My two workhorses, the steel wax-carvers at extreme left of the last photo, weren\'t great when I bought them - with flats where they should have had edges. I ground in edges, smoothed them with abrasive films and then polished them. The cream plastic tools were very basic too, with a pronounced casting seam that had to be scraped off and I then smoothed them with fine abrasives or steel wool before polishing them on a scrap of denim.
