I don't turn any of my pipes. I just use the chisels and gouges instead of the burrs. Makes a nice gouge channel. Gouges come in what's called "sweeps". A chisel is flat and gouges have a radius or the sweep. Pfile is a Swiss brand and one of the best. They also make high quality carving tools in England, Henry Taylor and Ashley Isles come to mind. If you're buying one you have to look for the width and sweep (radius) you desire. You have to be very careful when using gouges as the briar chips very easily, the top edge of the bowl and nomenclature pannel, end of shank are very dangerious areas for gouges especially if you're going for a smooth top. But you'll find that out if you use one
