It have found that it takes time and effort to become good at sharpening your tools. The time can be used learning how best to apply a system that is designed to handle all of your sharpening needs, or the time can be spend learning several different methods and systems because you do not have one system that will deal with all your needs. If all you ever do is sharpen a 3/4 inch bevel chisel and then use the chisel to scrape paint, you don't need a Tormek. If, you sharpen; plane blades, knives, bevel, mortise, shew and lathe chisels you may well be time and money ahead with a quality, comprehensive system such at the Tormek system.
