[The Story of the Hamatou Yifan Lineage]

The Hamatou Yifan lineage represents one of the most structurally unique and dramatic expressions in traditional wood-bone collecting culture. This rare mutation seamlessly weaves together two iconic biomorphic profiles:

• Hamatou (Toad Head): Outlines aggressively dropped, heavily swollen lower bellies that ground the piece with substantial physical mass and a beautifully rounded, low-slung base.
• Yifan Fengshun (Smooth-Sailing): Highlights a razor-straight, high-crested centerline spine that builds structural presence up the body like a raised court sail, tapering elegantly toward the crown.

In traditional cultural storytelling, the Yi Fan (Smooth-Sailing) architecture serves as an auspicious symbol of clear direction, unobstructed progress, and an unwavering, focused mind. Sourced from cold, high-altitude northern ranges, this lineage is fiercely coveted for its ultra-dense wood-bone fiber. The mature shell material is highly receptive to bare-hand handling, naturally absorbing lipids to transform from a warm golden-tan into a deep, high-gloss ruby-red patina.

[Product Characteristics of HMTYF-401E]

• Ultra-Agile 27mm Inverse Profile Stance: Measuring a slender 27.0mm edge paired with a full 35.0mm depth across the bellies. This striking 8mm inverse dimensional ratio creates an exceptionally compressed, vertically rich footprint. Purposefully scaled for nimble pocket format handling (Shou Nian), its slim width allows for effortless fingertip manipulation, while the full 35mm bellies actively track across the core of the palm for a satisfying roll.
• The High-Definition "Yi Fan" Spine: True to its Singularities pedigree, each piece showcases a beautifully straight, raised centerline ridge that runs perfectly aligned from the base up to the apex as seen in "1_14.jpg" and "3_10.jpg". This ridge provides crisp tactile definition and superior alignment tracking during manipulation.
• Swollen Basal Contours & Centered Navel: The underside showcases the definitive Hamatou drop, where plumper lower walls pinch perfectly inward toward a tightly compressed, clean central navel as captured in "2_11.jpg". This precise structural layout ensures the pair glides seamlessly past one another without catching or jamming during fast rotation.
• Resonant Iron-Bone Acoustics: Sourced from fully matured wild heritage lines, this pair carries significant unit weight relative to its compact footprint due to extra-thick internal chamber walls. When rotated or spun, the premium bone-dense material produces a sharp, clean high-pitched ceramic chime rather than a dull wooden clack.

[Maintenance Advice]

Because the "Hamatou Yifan" lineage features highly responsive, dense wood fibers with deep-set radiating valleys, it is highly recommended to keep this pair in a sealed bag when resting between handling sessions for the first month. This practice traps natural skin lipids to guide a uniform, blotch-free oxidation process across both the prominent ridges and deep recesses. Handling them directly with bare hands—completely skipping the use of gloves—is the definitive method to naturally develop a deep, high-gloss natural patina over time.
