I finally thought of an analogy which I hope seems parallel to this case.
Let's say I buy a Honda Civic. Nice, reasonably priced car without too many luxury features. It has seatbelts, air bags, headlights, anti-lock brakes. You know, standard safety equipment on any/every car in the US.
I decide to go for a drive in the country... at 11pm. Just because I'm lazy I don't turn on the headlights (guidance= rip fence not attached); I also don't take the trouble to buckle up, or I disengage the passive restraint seatbelts. (physical= TS on ground, crouching, using hands). And, just for kicks I floor it and close my eyes (just plain unsafe!= blade at maximum height, using hand instead of a push stick).
When I sail off the road, roll the car, and crash into something and fly through the windshield I decide to sue Honda.
Because, it is obvious gross negligence that they didn't install FLIR (which is available and technologically feasible in a car) so I could drive in the dark without headlights, even though I shouldn't. And they didn't install an ignition kill which should sense my seatbelt situation, even though I know I should wear it. And they also didn't install a speed governor tied to an eye sensor to make sure my eyes are open and I'm not going to fast, which is also technologically possible (i.e. eye-tracking for disabled persons). Wouldn't this be ludicrous? If it were just one thing it would be stupid. But take them all together and it is a foregone conclusion that something bad it going to happen!
Here's the thing: I'm not advocating for the above (far from it. And especially not regulation / government intervention). I'm firmly on the side of: You did dummo things with a bad result. Don't blame the company that makes a just-fine product. Take responsibility for your actions (or lack therof).
Now, if the TS he was using had suddenly exploded internally and thrown the blade into his hands, that is a different story. But this thing was functioning correctly, with no product defect or malfunction. The malfunction was with Mr. User, and mis-use of the product.
To Justinmcf: In recounting your mistakes did you think you should sue the tool manufacturer?
Or did you think in your mind "Holy smokes! That was stupid! I will never make that mistake again!"
