I used to use a knife sharpening service, realized it was a waste of money. Half the time the knives were returned dull.
Looking for suggestions on a knife sharpener for chef knives and serrated knives
Depends on the type of knives you have, are they German, Japanese etc… If German get a Norton Tri Stone they are fantastic. If Japanese get a wet stone with 1000 and 6000 grit. Hope that helps!
