How many blades depence on several things. On average, three or four blades is the most effective propellers. This is a relative small "monoblock", with high number of rpm i guess. But like submarine propellers has often 7 or 8 blades. That is less effective and cost more than your neibourhood. But they are stealthy! More than four blades gives less thrust. Ofcourse, the lighter the propeller is, the more the demands on the anomoly between all blades. Oh, I have no sound and bad Enlish, sorry)
