Blue Whale I
Blue Whale I is the first generation of Haifu's tacky forehand line. The topsheet grips the ball strongly and rewards a full brushing stroke, while the medium-hard sponge keeps the ball low over the net on pushes and short touches. It is a classic Chinese-system forehand rubber rather than a high-catapult European sheet.

Specifications and evidence
Approval evidence and market availability are recorded separately. A commercial listing is not proof of current ITTF legality, and an approval listing is not proof of current production. Approval is never inherited by an edition, and no expiry date is invented.
Market status describes current commercial availability only. A sold-out button or a low-stock warning is a stock state, not a discontinuation, and where availability could not be verified it stays unknown.
Haifu states sponge hardness on its own degree scale. Those values are preserved verbatim and are never converted to an ESN degree.
No reliable official Haifu list price is published per region, so no price is shown rather than an invented one.

TTDNA values are TTDNA's own editorial 0–100 ratings. They are not official Haifu measurements and are never a conversion of the Haifu manufacturer scale.
Haifu also sells glues and boosters such as Sea Moon and the Blue Whale glue and booster products. Those are not rubbers, so they are excluded from this catalogue rather than mixed into rubber filters or comparisons.

Editions and factory tuning
| Edition | Official label | Factory tuning | Sponge hardness | Covered by approval | Evidence |
|---|---|---|---|---|---|
| Commercial | Blue Whale I commercial | Untuned | 39° | Standard | Partially verified · Established specialist retailer listing |
| Provincial | Blue Whale I provincial | Standard factory build | 39° | Standard | Partially verified · Established specialist retailer listing |
| Training | Blue Whale I training | Untuned | 37° | Standard | Partially verified · Established specialist retailer listing |
Commercial, provincial, national and training editions are structured properties of one canonical product, never separate records. Factory tuning is stored per edition and is never inferred from an edition name, and an edition never inherits the commercial version's approval.
Factory tuning status is a separate fact from the edition level. Where no source states whether a sheet leaves the factory tuned, the status stays unknown rather than being assumed.

Data confidence
Generations are never merged automatically. Blue Whale I, II and III, White Shark I, II and III, and Pirates 07 and 08 are separate records, and no specification is copied between them.
Variants and configurations
4 variantsColour, thickness and configuration are variants of one model — never separate products. Colour never changes a rating, MAX and OX stay qualitative labels, and OX carries no sponge hardness.

Known users
Offensive club and league players who want a spin-first inverted sheet on the forehand or backhand.
Haifu publishes no athlete roster for this sheet, so TTDNA shows the player profile it is built for instead of invented names.
Rest of the Blue Whale family
Blue Whale II
The second-generation Blue Whale, with a firmer sponge and a faster, more direct response than the first version.
InvertedBlue Whale III
The most widely used Blue Whale generation: strongly tacky, with commercial, provincial, national and training editions.
