Sharpening Services

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 edges suited for the steel and knife or tool type. We can adjust edge geometry and blade thinness if necessary to provide improved geometry for sharpened in knives.

Turn around time varies for our sharpening service depending on how much work we have in. We tend to stay very busy even with several full time sharpeners working but we are happy to offer loaner knives when available. We also offer an expedited rush turnaround for an extra 50% fee, this is typically same day service.

If you are a professional cook or culinary student we can schedule your knives for rush service at the regular rate with one weeks notice, please be prepared to prove you use your knives or tools as part of your trade.
