When it absolutely positively has to come off NOW.

Makes sense and everybody in the world knows about this except me!

Safety glasses!! (Someone had to say it.)

I've seen the screw type. It stands to reason they would make a hydraulic one. 

I have the screw type. I've had very little success doing anything other than badly damaging the nut.

it is amazing how few people know about Nut Splitters.

Brings a whole new meaning to "the Nutcracker".

...shotgun? :)

THERE'S a ballet I would enjoy!

I got one just like that, just a bit older. Working on big equipment it's a life saver. 

That's cute, but it would never fit in the confined spaces where mine always seemed to be stuck. 

I witnessed my grandpa take a cold chisel and hammer to stubborn nuts on tractors and implements a few times in my youth.

I have had very good luck.  Check the "blade" of the splitter.  If it is getting rounded, buy a higher quality splitter.  If it is still sharpish, and your wrench force is just pulling it off of the nut, use an impact.

This.  I've used the screw type once or twice with success, but real world and automotive applications are limited.

I have a couple of tthe manual-screw type and whie they work well, they only work in places with lots of room to play.

That's a classic reference!

Yes, but wouldn't it have come off easier with some heat? (the back of the garage mechanic asks)

When that freshly applied paint cracked off, there was no rust underneath.  That nut would've come right off with a wrench.
