I would go so far as to say that the injury would be very similar if someones kids poked their fingers in either types of metal blades. Stainless steel probably 'looks' more dangerous.
In answer to the original rusting issue, either
1. paint metal baldes with a good enamel to prevent air coming in contact with the blades causing rust.
2. Buy non rusting blades ie good quality stainless steel/ plastic / timber.
