Having driven someone to the ER from a drone accident, just because they're not "sharp" doesn't mean they won't cut straight through your arms, hands, or wrist

Having driven someone to the ER from a drone accident, just because they're not "sharp" doesn't mean they won't cut straight through your arms, hands, or wrist if you touch them while they're landing. When the blades are going at ~10k RPM, it doesn't matter that they're made of plastic or whatever.
