Just bought a Sears Craftsman snowblower with the above warning sticker on it.
I can only imagine the dialogue across the Sears conference table:
"We have to show how dangerous machine can be. Should we show a limb in the process of being severed? What about blood?"
No blood in the final version, but I bet, over coffee and a nice spread, those corporate intellects vast and cool and unsympathetic regarded the visual depiction of the moment of limb mutilation in a series of serious, humorless meetings.
Heck, maybe there was a motion (made by a junior exec., I bet) to require a certain proficiency of customer IQ test results before allowing someone to buy a snowblower. But, well, this is America, and stupid people got money and Sears needs money, gang!
It's the jagged edge on the wrist that simultaneously horrified and startled me.
