CERTIFICATE OF AUTHENTICITY
At Tanzo Cutlery, authenticity is not a marketing detail it’s the very foundation of value. Every knife we make is limited, numbered, and truly singular. To protect that singularity we pair each knife with a physical Certificate of Authenticity and one half of a signed, torn U.S. $2 bill. The matching half is retained securely by Tanzo Cutlery. Together these elements create a verification method that cannot be replicated, copied, or forged—protecting the integrity and long‑term value of every knife that leaves the shop. This is honest protection for honest work. We build knives to be used but kept and we protect that promise with a verification practice as deliberate as the tools themselves.
Why a torn $2 bill?
The $2 bill is uncommon, tactile, and uniquely practical for secure pairing:
- Physical uniqueness: A tangible, hand‑signed, torn bill creates a simple human proof system that is impossible to reproduce digitally.
- Traceable pairing: Each bill half is matched to a unique serial number recorded by Tanzo Cutlery. The two halves form a one‑to‑one link between the knife and our records.
- Practicality: The bill is durable, recognizable, and easily photographed for verification without exposing our clients sensitive personal data.
How this protects your investment
- Uncopiable proof: A photographed serial number or sticker can be faked. A signed, torn bill paired with a retained matching half cannot be genuinely replicated, making counterfeit attempts impractical and easily disproved.
- Long‑term value: Because each knife is uniquely authenticated and documented, its provenance endures. Should the market for Tanzo pieces grow, verified provenance helps preserve and potentially increase resale or collection value.
- Ownership security: If you ever sell or transfer a Tanzo knife the COA and bill‑half system make verification straightforward for buyers and collectors, preserving trust across generations.
Verification & stewardship
- How to verify: Keep your half of the bill and the Certificate. If you need verification whether for sale, service, or transfer contact authenticate@tanzocutlery.com with the knife serial number and a photo of your bill half. We will confirm the record and update ownership details as requested.
- Lifetime service tied to authenticity: Your serial number and COA aren’t just for provenance. They are how we track your knife for free lifetime sharpening & repair ensuring the tool remains in service and its history intact.
Why this matters
We make one‑of‑a‑kind tools on purpose, limited runs, unique handles, all made by a single craftsman. These knives are meant to be used, kept, and cared for not copied. Our Certificate of Authenticity and the torn $2 pairing are built to protect that choice: the maker’s mark, the purchaser’s ownership, and the long‑term integrity of the Tanzo Cutlery name.
Frequently Asked Questions
What if I lose my half of the bill or the COA?
Contact authenticate@tanzocutlery.com as soon as possible. We’ll note the incident and advise next steps.
Why not use digital authentication or blockchain?
Our physical pairing is deliberately simple, human, and verifiable. Delivering a level of security that’s practical and permanent.
Can a buyer verify authenticity without contacting Tanzo?
A buyer can visually inspect the COA and bill half, but final verification requires contacting Tanzo with the serial number and photo to confirm the match against our records.
