Full chisel sharpening.

You can see the difference better from the other side of the chain. The full chisel has a square top edge not rounded like the semi.

I dont think that is the debate anymore . We are all agreed one is full chisel and one is semi chisel . The debate is now...... is one round ground and one square ground ?

This above from Dave ........ The far right being square ground full chisel . In the op's pic it seems there might be a semi chisel chain that has been square ground for some reason . .

To me it looks like it was sharpened with a thin grinder. The straight part is from the side of the grinding disk and the curve at the bottom is radius on the rim of the outside of the disk.

They're both brand new out of the box chains.

 

The middle one of Dave's drawings seems to be it.

I would say it most definitely is semi chisel. The first pictures shows that clearly Mick. The grind on the face looks square as opposed to a nice crescent.
