     You know "CLAD  metal " ?

  • It is a composite metal partly or entirely diffusion bonded  together of different kinds of metals.
  • Metal composition shows higher performance which respective materials alone do not possess and the performance complements opposite characteristics of each material, that is "compound characteristics".

Clad Effect on Cutleries

  1. Toughness
    Like Japanese swords, clad metal is hard to break or bend, thanks to the toughness as the hard steel part is clad with soft steels.
  2. Easy to work on
    Cladded structure is easy to apply on such works as forging, grinding, sharpening or polishing to make a sharp blade.
  3. Improved corrosion resistance    
    Proper material combination generates electrical potential difference and it enhances the corrosion resistance on blade edge.
  4. Better and long lasting sharpness
    Steel after forging pressure makes the microscopic structure denser and improves the sharpness and ensures long lasting performance.
  5. Resource saving
    As high class steel is used only for necessary part, it is perfectly cost effective..
  6. Easy distortion correction
    As the steel is bonded with soft steel materials, its blade is hard to break and the distortion correction is easy.
  7. Easy drilling and welding after heat treatment
    Though the steel gets harder after heat treatment, the soft steel never loses its softness, enabling the material to be drilled or welded.
  8. Design improvement
    Laminated patterns or Damascus patterns appear from basis materials which are bonded with different kinds of metals.
