Bringing Professional Sharpening Directly to Your Door

Welcome to Rejuvenated Knives

At Rejuvenated Knives, we blend cutting-edge technology with old-world craftsmanship to provide an unparalleled knife sharpening service.

Rejuvenated Knives was founded by Martin, an aerospace engineer with a successful 12-year career in the optical communications industry. His passion for precision engineering and solving everyday problems inspired him to rethink the traditional knife sharpening experience. The result is a service that combines meticulous craftsmanship with modern convenience, making professional knife sharpening faster, easier, and more accessible than ever before.

We understand the busy schedules of professionals, home cooks, and anyone who values quality kitchen tools. Our mission is to eliminate the hassle of maintaining your knives by picking them up, sharpening them to a razor-sharp edge, and delivering them back to your door—typically within about an hour—so you can spend less time running errands and more time doing what you love.

What Industry Pros Are Saying

“Best sharpening service I’ve found in 15 years. As a chef, I trust Martin with my essential knives. He uses top tools and techniques and always delivers amazing results. Now I have more time to cook, and my razor-sharp blades give customers a better experience. Thank you Martin!”

Mark Sethi

Owner and Chef That’s My Jam in San Francisco

“They sharpened 50+ pieces for our food science lab. Noticeable improvements in performance and consistency.”

Aaron Lurie

Impossible Foods

“Martin was very responsive and knowledgeable in his line of work and would trust him to handle my expensive knives. On top of rust, the service was also very affordable as well as convenient. My knives were sharpened on a whetstone and finished on leather and alumina polishing compound which is a 8000 paste, leaving the edges nicely polished and sharp as razor blades.”

Kenneth Luu Chef de Partie Ethel’s Fancy

Palo Alto CA

“Talk about a sharp business! (pun intended) Marty runs a friendly, convenient and most of all service oriented shop. If you need your knives to behave like, well, knives, do not hesitate to call Rejuvenated Knives.”
