This Classic AnySharp knife sharpener will work with almost any knife type, including fancy-pants chef’s special hardened steel knives. The only blade types not recommended are fine-toothed serrated knives. Regular serrated knives, such as bread knives or hunting knives, should be fine. The fact that AnySharp is small, round, feels reassuringly solid (being primarily made of metal) and takes up very little countertop space. The suction-cup bottom is reliably secure and means you can whap the AnySharp down wherever you need it, lock it in place and quickly sharpen the blade in your hand. You could even stick it to the fridge or kitchen wall tiles in this way to keep it handy. So the next time you think of throwing out that blunt knife, think again.
To sharpen your blades, you simply draw the blade slowly and gently between the overlapping tungsten carbide ‘teeth’, preset at an effective 20-degree angle, marvelling at the fine metal dust being pared off your knife, meaning you can literally see your knife getting sharper.
