[Kondo] Bishan Coarse Finish Hammer (16 Carbide Bits - 4x4 Grid) with Oak Handle [KMF020101]

This handcrafted [Kondo] 16-bit Bishan is a single-faced stone finishing hammer designed to rapidly level uneven surfaces and impart a bold, rustic non-slip texture. In contrast to standard Japanese trade practices where heads are sold separate from handles, Tetsufuku delivers this tool pre-installed with a high-grade Japanese oak (Kashi) handle to ensure perfect ergonomics straight out of the box. Featuring a 16-bit (4x4 grid) tungsten carbide layout on one face, this configuration concentrates your swing energy across fewer points for efficient material reduction. It functions perfectly for dressing building blocks to establish stable planes in Dry Stone Walling (DSW), prepping foundational elements for Niwashi (Japanese gardeners), and texturing architectural masonry with an authentic artisanal feel. While traditional temple masonry utilized higher bit counts for micro-fine surfaces, modern landscape design relies heavily on the 16-bit pattern to achieve robust slip resistance on outdoor paths while preserving the natural weight and rustic flavor of the stone.

⚠️ WARNING: This is a single-purpose finishing tool operated strictly by swinging the carbide face directly against stone. The flat reverse side of the head is composed of unhardened steel; you must never use this reverse side to strike stone, nor should you ever hit the reverse side with a Setto hammer, as the head is not structurally treated to withstand metal-on-metal impacts and will deform. Always deliver flat blows to protect the brazed carbide tips from asymmetric shearing stress. 16 bits(2*2) to 64 bits(8*8), and this is a product of 16 bits(4*4). The fewer bits, the coarser finish, and the more bits, the finer finish.

The notes on use about Bishan, coarse finish hammer (16 Carbide bits) [KONDO]

Hammer a stone softly, rhythmically and vertically by all means. The properties of steel and carbide is superior in wear resistance and it is the harder, the more fragile. Conversely, soft steel and carbide are superior in durability and shock resistance. This product has been setting hard condition, if you wield or hit strongly, there is a possibility that brass brazing will break. In addition, it is a main factor of breaking to hammer a stone diagonally. Please hammer a stone vertically by all means. The Japanese craftsmen using our product habitually know this point well enough, but we would like overseas users to keep it in mind.
