Choosing the right edge geometry and finish are key in producing a sharp and durable edge for the desired use of the knife

Bernal Cutlery specializes in wet grinding and Japanese whetstone sharpening using techniques that provide sharp edges that are appropriate for the specific steel and knife type.

Time-honored Japanese whetstone techniques mean that we use a variety of grit sizes before we finish by hand with a modified version of an old fashioned Barber’s strop. Japanese whetstones are not only the preferred sharpening medium for fine Japanese knives, but are superior for all types of cutlery. All larger scale metal removal is done with water cooled Japanese and Swedish grinders that will not burn the temper or remove unnecessary amounts of metal. We adjust edge geometry and blade thinness when necessary to provide improved geometry.

Turn around time is typically between 5 and 8 days. We offer same-day rush for an extra 50% fee. If you are in the industry and work with your knives please call the shop at (415) 355-0773, we are able accommodate industry schedules, please be prepared to prove you use your knives or tools as part of your trade.
