Before you ask
A written opinion of current market value for your personal decisions — selling, buying, or negotiating. It is an informed estimate based on observed market data, and it is a formal insurance or estate appraisal's simpler cousin, priced accordingly.
Every report is drafted with KnifeData's market engine, then reviewed, edited where needed, and signed personally by Ryan Dennis. A report ships only after a person has read it.
Private collector-to-collector sales, public marketplace forums, and first-party store records. Individual sellers, buyers, and communities stay anonymous — always.
Full refund, with a note explaining why (usually: too little market evidence or an identification we can't pin down from the description).
Within 24 hours of payment, usually sooner.
