Scissor Sharpening Question.

Larry777, remove the nut and they come apart. Now sharpen each half by laying them on the inside flat (where they rub against each other).
Lay it flat on a fine oil stone like an India and rub it into the edge. Using light pressure rub it 5-10 strokes, that's all. Then do the other one.
Put them back together and cut some paper. They should cut better. They don't look in bad shape. So, they shouldn't need a lot of work. DM

 

Hi
Are you sure about that?
Isn't that the classic scissor sharpening mistake?
Thats like sharpening a chisel by flattening the back of the chisel ... except scissors often have a subtle curve towards the tip

 

If the scissors have flat grind across the ride (inside bearing surface) you can take them apart and grind some of it to help reset the bevel. If it is a slight hollow grind you should not do more than a few passes unless you have a grinding wheel and are resetting the entire underside - per hair shears.

For regular scissors just grind the last bevel where the two sides meet, there is no need to grind the upper face. Utility scissors are not like two knives, they are like two roller shears - the edges can be close to 90° and will still cut well because the two surfaces work as a team.

Hair shears are set at a lower angle and have a bunch of other characteristics that make them an entirely different animal, starting with most have a slight twist from the plunge to the tip (helical), they cannot be safely worked on the inside face without ruining the set.

 

I didn't really want to get into all that as this is a dark tunnel he is about to go down. DM

 

I've sharpened a few thousand scissors and have never ground the inside flats... which are not actually flat.

Cheap scissors are a pain to sharpen with a stone but can be very easy on a belt sander. The easiest method is to simply sharpen the ground bevel until a burr burrs on the inside flat then put the scissors back together and cut a sheet of paper a few times. This or just opening and closing the scissors a few times will remove the burr and leave you with sharp scissors.

 

Larry, some scissors do, others are like Heavy describes, having a slight hollow grind. For now try working just one side of their blade angle.
The flat side. DM

 

if you have a ceramic rod or sharp maker you can hone the edge and get it pretty sharp quickly.
