IIRC 80% of sink disposals in the US are made by Insinkerator, under
several or quite a few brand names, including house names.
If it has a hex hole in the bottom center, it is probably
Insinkerator. Off brands are maybe 5% cheaper but might have a year's
shorter warranty (2 instead of 3. Don't recall the high end
warrantees.)
OTOH, with my 1 step from the bottom disposal, I couldn't really get
any pry-bars in, so maybe yours is made by someone else.
The wrench that fits the hex hole in the bottom is very convenient,
but not very long. But I could turn it pretty hard. The problem was
that the disposal itself started turning and I was afraid I would
break the outlet pipe or the drain. And the torque was limited by the
fact that the whole thing started turning.

Both of mine have rusted shut. But I don't use them for grinding up
waste I *put* in the sink, only for things that accidentally fall in
the drain. Once every month or two. They still lasted about 10 years
each. No wear. Just rust. :) With this new one, I plan to run it I
guess once a week. No need to use water if one is running it only for
5 seconds.
I lost a washing machine once because I didn't use it often enough.
The main bearing inside the agitator rusted shut.

When my first one froze up, I tried to take it apart. Other than
obvious trim, the top of the intake chamber, I don't think I got a
single part off.
