Named for the year of Zwilling's founding in Germany, the Twin 1731 series is a collaboration with internationally acclaimed designer Matteo Thun. Zwilling's 7-piece set includes essential knives — paring, santoku, chef's, bread and carving — along with a stunning vertical block that safely stows the razor-sharp blades while showcasing their beautiful craftsmanship. The precision-forged stainless-steel blades are honed and hand-finished by skilled artisans for maximum sharpness. Their innovative curved bolsters work as an extension of the hand, supporting a professional grip with thumb and index finger on the blade.

  • Knives are precision-forged from a single piece of Cronidur 30 high-performance stainless steel.
  • Zwilling's Sigmaforge process incorporates the Friodur ice-hardening technique to produce corrosion-resistant blades that are exceptionally hard yet flexible.
  • Curved bolster promotes a grip for greater precision, safety and comfort.
  • Untreated, oiled ebony wood handles.
  • Ash wood block doubles as storage and display.


7-Piece Set includes:

  • 4" paring knife.
  • 7" santoku.
  • 8" chef's knife.

  • 8" carving knife.

Use & Care


  • Always use caution when handling sharp objects.
  • Avoid cutting on hard surfaces such as stone, metal or glass.
  • It is not advisable to use any knife but a meat cleaver to cut through bone, as other blades can be easily damaged.


  • Hand-wash with warm water and a mild detergent; rinse and dry immediately.
  • Avoid cleaners containing bleach or citrus extracts.
  • Sharpen as needed. With regular use and honing once a week, you should not need to sharpen your knife more than once or twice a year.
  • Sharpen your knife at home using a whetstone or knife sharpener, or have it sharpened by a professional.
  • Store knife in a safe place to protect its edge and prevent injury.
