A standing watch
Japanese knives and whetstones, watched as they are listed.
Bladehound follows public marketplace listings for Japanese kitchen knives and natural whetstones. Each listing is read for the signature on the blade, the maker is identified against cited references, and a value is estimated from public marketplace data.
Every figure it shows is an estimate, and every listing states the evidence behind its own number.

How it works
01
Watch
Listings are collected from public marketplaces as they appear. Nothing is bought, nothing is sold, and Foodgeist takes no part in any sale.
02
Read
The mark on the blade is read from the listing photographs and matched against cited maker references. When no signature can be read, the listing says so rather than naming a maker.
03
Estimate
Where recorded sales of comparable pieces exist, a value is estimated from them and the number of sales behind it is shown. Where they do not exist, the listing shows a researched range and says it has no recorded sale behind it.
On watch right now
Every listingRanked by asking price against the estimated value. Only listings that carry a ranking appear here, so this is a slice of what is on watch and not the whole of it.

About these estimatesClose
The values and identifications shown here are estimates generated by an AI system from public marketplace data and statistical models, and AI can and does make mistakes. They are offered as a helping and research tool, not as a definitive answer, appraisal, or authentication. Every figure is a statistical estimate, not a promise: no value, and no accuracy, is guaranteed. Nothing here is financial or investment advice. Foodgeist accepts no liability or responsibility for decisions made using this information. Before buying anything, do your own due diligence. Check the listing, the seller, and the item yourself.
What this is not
Not an appraisal
The values here are estimates produced from public marketplace data. They are a research aid. Accuracy is not guaranteed, and an estimate is never an authentication of a maker or a piece.
No track record
No item on watch has been bought, resold, or checked against a sale that actually completed. There is no record of outcomes to report, and none is claimed.
No whetstone values
Whetstone ranges are placeholders. They are not drawn from recorded sales of the stone in question, so those listings carry no value badge at all.
Not advice
Nothing here is financial advice. Check the listing, the seller and the item yourself before buying anything. Foodgeist accepts no liability for decisions made with this information.
