Almost every set of turning tools comes with a spear point chisel. If I go on You tube, there are hundreds of videos about use and sharpening of gouges, nearly as many about use and sharpening of skew chisels, probably dozens of videos about use and sharpening of scrapers. But not a darn thing about a spear point. Two friends just re ground their spear points to be scrapers. Are they really as worthless as that?
