I believe the answer is:

pencil sharpener

I'm a little stuck... Click here to teach me more about this clue!

This might be a double definition.

'stationery' is the first definition.
(I know that pencil sharpener is a type of writing implement)

'item probably not much point going into it' is the second definition.
I know that 'point' relates to this answer.

Can you help me to learn more?

(Other definitions for pencil sharpener that I've seen before include "that makes lead go further" , "shaving device" , "Desk item" , "something struggling writer might resort to" , "It's used to make a point" .)
