The Japanese mortise bottom cleaning chisel (Soko Sarai Nomi) is a specialized tool designed for cleaning the bottom of mortises and drilled holes . Unlike conventional straight chisels, its sharply angled shaft and wide cutting angle allow easy access to the bottom of cavities without hitting the sides.
This tool is used after the main digging work to efficiently remove chips, sawdust and residue , ensuring a clean and even base, essential for precise and durable assemblies.
Compared to the yari nomi (spear chisel) , this model features a more pronounced curve and a geometry optimized for material removal rather than penetration. It is particularly valued in traditional joinery, Japanese carpentry, and restoration .
As each piece is handcrafted, slight variations may exist, reflecting the manual work involved.
