Sew Interesting

Fun finds.
Seems to be I am finding sewing goods lately.
Like this red, plastic spool holder.

and this Anne Adams dress pattern. complete with envelope.this trio of treasures..

and these unique scissors.

Anyone know what these are for?
I mean what's the purpose of the notched part?

Thanks for coming by.
So grateful you all stuck with me while my
computer was down,and I did not get to post much.
