[Kondo] Bishan Coarse Finish Hammer (16 & 25 Carbide Bits - 4x4 & 5x5 Grid) with Oak Handle [KMF020201]

Masterfully forged by [Kondo], this double-faced Bishan is a premium multi-grit stone texturing hammer engineered to flatten uneven rock faces and add architectural character. While standard suppliers distribute these components separately, Tetsufuku provides this tool pre-installed with a rigid Japanese oak (Kashi) handle for optimized swing control and out-of-the-box readiness. This specific model features a dual-active head combining a coarse 16-bit (4x4 grid) configuration on one face and a medium-coarse 25-bit (5x5 grid) configuration on the opposite face, giving craftsmen two distinct finishes in a single tool. It serves as a vital implement for removing remaining point-marks on building blocks in Dry Stone Walling (DSW), and creating tasteful, non-slip rustic textures on stepping stones, pathways, and garden lanterns for Niwashi (Japanese gardeners). While historic Japanese masonry favored ultra-fine, perfectly uniform surfaces for sacred shrines and temples, modern landscaping frequently utilizes these configurations to provide practical slip resistance underfoot while showcasing the organic flavor of the stone.

⚠️ WARNING: This hammer is operated strictly by swinging the tool directly against stone using your own arm energy; because both active faces are integrated with hard tungsten carbide tips, it has no steel striking face and must never be struck with a Setto hammer, as doing so will instantly shatter the carbide or break the brazed joint. To prevent the carbide teeth from fracturing under load, ensure the head strikes the rock face perfectly flat on every swing, avoiding angled or glancing blows.
