Waterstones do require practice – it's a bit of faff, in all honesty, though rather therapeutic once you get the hang of it – but they'll keep your knife in tip-top condition, so it's worth the extra effort. If you're worried you're doing it wrong, look up your local knife manufacturer or kitchen shop, as many will offer sharpening classes.http://www.taideasharp.com/kni....fe-sharpener/manual-
