bera in mind that You can sharpen with a lots of items. Elecriclas rotating elements (to me a very poor choise) or by hands (best choise). By hands you have stll to decide wich way You likemore: whater stones (like some naturals very difficoult to find, ie european pleistocene era stones or japanise diffrent grades natural stones) oil stones (ie arkansas honey or grey) or reconstructed-artificial stones (worst of all). Or you can go also with diamonds sharpener or sandpaper differents grit+mouse pad (n this case you'll get a bombed blade). Once you make your's choise its' only a matter of practicing and practicing: diferrent corners, different steels and blades shapes, different force applied: but youl'lfind you way for shure.
