Your new knives should last forever if you take care of them.  Good knives should never be put in the dishwasher.  Always hand wash and dry right away.  Never leave them sitting in water for extended periods.  They can rust and the pakkawood can swell.  The reason is that good knives are not made from pure stainless steel.  They are made from a mixture of high carbon steel and stainless steel.  The high carbon allows the knife to be sharpened and the stainless keeps it from staining.  However, the detergents and heat in a dishwasher are too much for the mixture and all good knives will rust in the dishwasher.  Always use the honing steel to realign the edge before use.  This should be done before every use.  The honing steel straightens the edge.  It does not sharpen.  The diamond steel should be used approximately once a month or when your knives don’t feel sharp after using the honing steel.  The diamond steel has powdered diamond dust to remove a small amount of metal to get your edge back.  If the diamond steel and honing steel doesn’t work its time to use a V sharpener.  The V sharpener will strip off the old edge and put on a new one.  But try not to use it too often as it will wear your blade away after time.   For a complete tutorial on how to use the sharpeners and all other knife skills, please take our knife skills video class by clicking here .
