Follow the model's safety and loading instructions for sharp utensils. Do not create an exposed sharp-point hazard merely to fit more items into a basket.
Understanding this situation
Some machines provide a particular tray or horizontal position, while the knife maker may restrict machine washing altogether. Safety and item suitability need checking before cleaning performance.
A useful next step
Use the approved arrangement and keep children away from loaded sharp items. If a knife cannot be secured safely, use another appropriate cleaning method. Do not assume a successful wash makes an unsafe loading position acceptable.
