Why Customers Upgrade

Five Stars ⭐⭐⭐⭐⭐
“I didn’t think it would make such a difference, but wow. My knives came back sharper than I’ve ever had them! Totally worth adding the whetstone finish.”

– Chef Marvin Trevino

The Japanese Whetstone Finish is a premium add-on that gives your knife a refined edge using traditional Japanese water stones. It’s the final polish that unlocks the knife’s full sharpness, smoothness, and precision.

Ideal for: chef’s knives, high-carbon steel knives, and Japanese knives.

Please note: This is an add-on and must be purchased alongside a knife sharpening order. If sending multiple knives but choosing the Whetstone Finish for only some of them, please label those knives clearly using the sleeves provided in your kit.

Subscriptions: The subscription frequency must align with your selected knife sharpening schedule.

Common Questions

What exactly is Whetstone Finishing?

Our Whetstone Finishing service is a hand-sharpening upgrade that takes your edge beyond standard machine precision. After your knife is shaped and refined through our controlled grit sequence, we continue by hand across Japanese waterstones up to 8000 grit.

How is Whetstone Finishing different from a standard sharpening service?

Our standard sharpening delivers a precise, factory-level edge using ceramic belts up to 2500 grit. Whetstone Finishing builds on that base, introducing true waterstone refinement. Each stroke is guided by hand. The result is a smoother, cleaner, and more precise.

Which knives benefit most from Whetstone Finishing?

Any knife can benefit, but high-carbon steel, Japanese-style, and premium chef’s knives gain the most noticeable improvement. These steels respond best to fine waterstone work, showing better bite and glide.

Can you whetstone-finish serrated knives?

We can refine the flat edge sections, but fully serrated knives are handled with specialized tools, not waterstones.
