I have cought a couple of falling razors myself, and dropped some too... At first, I always caught them... Then, I imagined slicing tendons or something - and decided it's probably better to let it go and hope for the best / minimal damage. I have fairly quick reflexes and lately when I do catch the razor it's just an instinctive (if / and wrong) reaction before I can think what's best / assess the risks

Cheers
