  • Diamond and tungsten steel — fast, effective sharpening
  • Suitable for most blade types — one stone for the whole knife block
  • Single stone or full set — pick what suits your kitchen
  • Several colours and finishes — including marble-effect options

A small kitchen essential that makes every cutting task noticeably easier.
