“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.

I decided to try the whetstone finishing upgrade, and I’m so glad I did. The difference is incredible - my knives don’t just cut, they glide through everything now. It’s the kind of sharpness you usually only get from brand-new knives, and it’s held up beautifully. If you’re already sending your knives in, this little upgrade is absolutely worth it.
I honestly didn’t realize how dull my kitchen knives had gotten until I tried these guys out - and wow, what a difference. The whole process was so easy. They sent me a protective kit with sleeves and a prepaid label, so all I had to do was drop it in the mailbox. A few days later, my knives came back sharper than ever. I loved concept - just pack, ship, and done. I’ll definitely be using this service again!
Top notch sharpening. Straightforward and quick, the turnaround was exactly like they said on the site. Really clean job, sharp and straight. They sent stickers in the envelope when my knives came back too :)
Fast, affordable, convenient and reliable. Couldn't ask for anything more!
Love this company! The process was so easy, I placed my order, got the kit a few days later, packed my knives in about 3 minutes, and sent them out. Just a few days later, my knives were back, sharper than when I first bought them (sounds crazy, but it’s true!). I would highly recommend!
