Sharpening services

Professional Knife sharpening service


Our skilled knife sharpener will select the best whetstone for each knife by looking at the material, quality, and condition of the knife and carefully sharpen it, constantly fine tuning to get the perfect finish. Many sharpening services use aggressive industrial machinery that overheats cutlery destroying the temper and geometry of the knife. At Kataba we offer a traditional Japanese sharpening service using waterstones, if heavy grinding is required in a repair we use electric rotary waterstones or a belt sander equipped with special ceramic belts but the majority of our sharpening is performed freehand using both synthetic and natural Japanese waterstones; this system of sharpening removes the minimal amount of steel necessary and ensures a stronger, finer edge that will last longer. Our expertise and skill in sharpening will bring out the best cutting ability possible from your blade. Our patrons often say that their knives now cut better than when they first bought them and we have many repeat customers. Please come and try our knife sharpening services, which are appreciated by both customers left unsatisfied by other sharpening service providers and pro chefs.


*We strive to provide the best service possible and return knives as quickly as we are able but cannot guarantee knives will be completed within a specific timeline. Single bevel cutlery and heavy repair work require a minimum of 72 hours before completion.
