This copper herb grinder dates to the mid-to-late 20th century and features a boat-shaped trough supported by three-legged stands on either side. The interior is finished with red lacquer, while the exterior wall is engraved with the character Zen, blending practical utility with Zen aesthetics. The grinding wheel and handle combine copper and wood, faithfully replicating the structural design of ancient herb grinders with exquisite attention to detail. It serves not only as a collectible piece representing Traditional Chinese Medicine culture but also as a vintage decorative accent for tea settings or studies.
