Additionally, if you fear the little thumby protrusions contact with the razors edge you can fold back your hand and you'll see lots of rounded protrusions with which to clean a razor with, then rinse your off hand, which can bang on the faucet all day long. My fav area is the entire side opposing the thumb, you can slide the blade outward from your hand without ever sliding your hand/thumb down the edge. That thought even concerns me a little, yet it is perfectly safe.
Dylan-for once your very wrong, your not the slowest learner. :)
