CocoboloWood grain, brass inlays and separate mechanical parts
A red-brown wooden face can carry carving while surrounding a separate mechanism.
Pinganfu 2.0 combines cocobolo with brass, while the Fanhua blank mahjong slider pairs its wooden face with PEEK components. Both leave the grain visible, with different arrangements inside.
Unassembled wooden parts, an open slider and a group of mahjong pieces show three ways to look at machining, component placement and variation in grain.
Wooden parts for Pinganfu 2.0, before the brass inlays and internal components are fully assembled.
Carved wood outside, brass ball recesses inside
The open red-brown cocobolo version reveals its brass inner structure. The neighbouring African blackwood piece uses a different wood.
GD EDC’s June 2025 Pinganfu 2.0 announcement lists a cocobolo version with brass inlays. The front carries an antiqued, hand-polished metal inlay with the characters for “peace”; the back has the character for “good fortune” carved deeply into the wood. Grain and carved lines meet on the same surface.
Opening the slider reveals the tracks and ball recesses in the brass inner structure. The announcement separately lists a POM travel-limiting centre post. The wooden exterior, brass interior and centre post each have a distinct role. The neighbouring dark African blackwood piece is another wood version.
Two balls for this particular release
This cocobolo Pinganfu ships with two balls, in what GD calls “scale mode”; the African blackwood version ships with one. Both use the interleaved track for this release, so the wood choice and supplied ball configuration belong together.
GD also says later releases will come with different tracks. These details therefore apply to the June 2025 update. Sound and feel labels remain the maker’s descriptions.
One lattice motif, many grain patterns
Cocobolo faces on the Fanhua blank mahjong slider: the same carved motif sits over different natural grain patterns.
GD’s April 2026 exhibition announcement describes the Fanhua-themed blank mahjong slider as combining PEEK with a traditional window-lattice body, and names cocobolo as the wood. The group photograph shows the same carved motif across faces with different tones and grain directions.
The wood does not account for every component. The original disassembly photographs show pale track components alongside the wooden part and identify two alternatives, A and B. The clean exterior photograph used here focuses on the relationship between carving and grain.
Grain variation and care for this product
The Pinganfu 2.0 announcement notes natural pores, growth openings and grain, with patterns supplied at random. In the unassembled-part photograph, dark lines, the red-brown background and machined openings can be examined separately. GD also describes selection, pairing, machining and hand finishing.
For this wooden product, GD advises avoiding water, alcohol and other liquids that could affect its oiliness and appearance. Other finished pieces should be considered according to their own surface treatment and maker’s care instructions.
A reference for the name Cocobolo
China’s national forestry authority links the Chinese name Weiao Huangtan to Dalbergia retusa, while the US Forest Products Laboratory’s wood sheet names Dalbergia retusa as Cocobolo. Together, these provide a reference for the Chinese and English names used here.
The wood in these particular products is still recorded according to GD’s description of Weiao Huangtan. A name correspondence is separate from authentication: the wood in each finished piece has not been independently identified here.
