"door knob" and "door's knob"

[jctgf]

hi,
I wonder if both are possible in English.
can I say that "door knob" means a knob for doors in general and that "door's knob" means the knob of a specific door?
for example:
1) where's my shirt? it's hanging on the door's knob, don't you see?
2) please, do you have door knobs?

thanks,
jc

It's possible to say something about the knob of a door the way you did it above, but normally you say door knob.
