Frequently asked questions

Can I dishwasher my knives?

We do not recommend dishwashering knives for a number of reasons:

  • Dishwasher salt is corrosive and will ‘eat’ into the steel on the knives causing rusting issues.
  • The heat in dishwashers can react with the metal in the handle causing it to expand. This in turn could cause cracking of the handle.
  • The heat and salt in dishwashers turn the stunning black handles into charcoal looking handles over time.
  • If you place a knife blade-down in the dishwasher basket, you are blunting it unneccesarily. If you place a knife blade-up – this is an extreme health hazzard when it comes to removing it from the dishwasher.
  • Dishwashering of I.O.Shen knives invalidates the life-time guarantee.
