since I want to hand sew my own clothes and stuff I need decent tools, including dressmaker shears. but a reputable one is an investment, and I already splurged my spending money on ropes 
I have these shears lying around that are from a reputable brand, but they're in terrible state 
can we make these become a "decent tool" again, and avoid more consumption? I guess if you disassemble them, vinegar the rust away a bit, then file away the rest, then sharpen… I've never tried sharpening scissors, but I have a whetstone somewhere… could even spray that handle to redo the painting while I'm at it?

says that vegetable oil + 10% acetone is as good a penetrating oil as wd40
- Japanese people use tsubaki oil on blades
- I have both tsubaki oil and acetone
I don't have steel wool here tho 
would 600-grit sandpaper be too abrasive for it, do you think.
it feels weird to remove rust from metal then just leave it exposed without any type of varnish or anything (I mean not the cutting edge, the body of the blades). but since all scissors are like that I'll assume they don't work well if you paint over. maybe it's not smooth enough?
in any case I'll take care to keep them oiled, the jojoba oil I got for my ropes should do as well as tsubaki.
@elilla I mean, it's stainless, it's supposed to work like that. You can probably oil it a little
