For awhile I really couldn't figure out why so many people have a problem sharpening an edged tool. I own a single medium/ fine AG Russell bench stone and I use this on my axe, knives, German Kinetics Silver Flames Zwickeys, Woodsmans, Simmons, etc and it matters not. No special methods and no guides. There are only two tips you need. One is you must only use the the weight of your blade or hand for pressure, bearing down will not make the work any faster. Second you must buy a quality stone. That is a quarried natural stone, dmt diamond, or KME ceramic. Nothing else will do and it will cost you some doughage. A $5 reconstuted stone is more valuable for removing lime stains of a toilet.
