Handle up. Items one at a time in the silverware bins, starting over again when I reach the end. Specialty knives, then steak knives, then butterknives, then forks, then spoons. Enough information for you?
If you put your knives in handle down, then the sharp point of the knife will rub against the basket material during the dishwasher action. If the basket is metal, the knife will get dull. If the basket is plastic, the knife will damage it.
Wow, this is an intellectually stimulating thread!
