No, a knife cannot scratch a diamond. Only a diamond can scatch another diamond. Diamonds can scatch other diamonds. Diamonds have the maximum of hardness 10 on Mohs Scale of Hardness (that goes from 1 to 10, diamond is 10 and chalk powder being 1 for instance) because of its very compact crystal structure.

What are diamond knives made of?

These blades consist of a steel core (the base is steel plate, unlike that of the wires used in diamond wire saws) and diamond segments, which are made by combining synthetic diamond crystals with metal powder and then sintering them. The diamond segments are also known as the “cutting teeth” of the blade.
