A Japanese saw, also known as Noko Giri or Ryoba saw, is a traditional Japanese hand tool used for cutting wood and other materials. Unlike Western saws, which are mostly straight or serrated, the Japanese saw has a very thin blade with backward-facing teeth.
Joint Crack
Joint cracks are cracks that occur in the joints of structures, especially in masonry, tiles, or concrete slabs. They often arise from material movements, thermal expansion, or material shrinkage. Joint cracks can cause both aesthetic and structural problems, as they allow water and other harmful substances to penetrate, which can lead to more serious damage over time.
