The skin itself is equally sensitive everywhere.

There are less never endings in some places then others, but the skin is equally sensitive.

I'm no dermatologist, but I don't believe that's correct. No matter what the nerve ending density is, skin can be callous or not. I would pose that there're parts of skin which are less sensitive than, say, the heel, which is typically very callous.

A callus is dead skin.

Then the answer to the least sensitive skin is dead skin.

(I really hate not being able to edit posts.)

I guess it depends on your definition of "sensitive". I believe that the first two definitions, listed on dictionary.com for the word, cover the two different things we are thinking about:

1. Capable of perceiving with a sense or senses.
2. Responsive to external conditions or stimulation.

Less nerve endings would result in less capability to percieve sensation, while calloused skin would be less responsive to external stimuli.
