Border and corner puch
Unfortunately this did not include the corner punch which I was under the impression it was. However, I have used the border punch and the result was not a good as expected either. When the lever is put to 2 edge punch it only does one edge and makes a series of holes on the second edge which needs to be cut off.
It really is only a 1 edge punch which is very disappointing as I already have a single edge punch.
