Let's just put this argument to bed shall we? Let's consider another case. Leatherman pocket knives. It has a ~20% chance of cutting you, a 5% change of killing you if it pieces the wrong place in your body. I'm speaking from experience, where I sliced my thumb open (by accident of course!), but it was quite bad that I severed a nerve.

Needless to say, I don't feel compelled to take a moral or ethical stance on the use of such tools -- in this case; pocket knives and their inherent dangers.

Every time no matter how sophisticated or the no. of safeguards you put in place, can still inherently pose risks.

I'm not even arguing about food safety. Just think about the many restaurants that prepare and cook up the Japanese pufferfish. That's not even a tool problem right there, that's a skill and trianing problem. That shit™ will can can kill you if not done right.
