1) cat < K1 K2
The above operation should actually display contents of the both files.

I'm curious, what makes you think it should do that? My man page states
Quote:

Concatenate FILE(s), or standard input, to standard output.

(my emphasis), which I understand to mean "not both", i.e. if you give cat a file to read from, standard input is ignored.
Code:
cat > K1 K2
