Do you require a smooth razor keenness or a toothier bite? Choosing the right stone and using it at the right time are key in producing a sharp and durable edge for the desired use of the knife
Bernal Cutlery specializes in Japanese whetstone sharpening and finishing using techniques that provide edges that are sharper, longer lasting and require far less metal removal than dry grinders and belt sanders, which are too aggressive and remove unnecessary amounts of the blade and often mar the knife with scratches and other scarring in the process.
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.
Turn around time is typically between 3 and 6 days, but rush/same day service is available by appointment. Knives can be dropped off at the store at the corner of Guerrero and 18th, mailed-in, or dropped off at one of our convenient drop-off locations. Same-day sharpening appointments can be made by selecting the desired date from the Sharpening Calendar at the bottom of this page.
