The shiny blade is blinding you. Most of the bevel is useless and not used
in cutting. It is the edge where the blades meet that counts, you need
clean angle matching the bevel angle. Any rounding here is what amounts to
dull. Try flattening the back of the blade by filing there too
Also if the pivot point is adjustable, you want it tight but not so its hard

A file probably won't get them sharp enough, you need a sharpening

along your thumbnail as if you were trying to shave it (away from your
thumb!). If the blade slides easily and doesn't catch, it's dull.
If you get the blade sharp and it still doesn't cut, then the blade
might be bent or as another poster said, the pivot is loose. As you
close the shears, one blade should slice across the other with the
contact point moving from the pivot side toward the end of the blades
as you close them.
Ditto comments on two prior posters.
Make sure the bevel and the flat back of blade are both bevelled, and flat,
respectively. For reshaping the bevel I use a carbide abrading tool such as
Files are nearly useless in my experience, as they produce an uneven, notchy
I put the blades in a vise, do the bevel with the carbide tool, then finish
and deburr with a regular carborundum (silicone carbide) sharpening stone,
using it also to flatten the back of the blades.
Make sure the pivot screw is tight, and hinge is oiled.
