Edge banding advice

In a couple of weeks I will have a little repair on some kitchen cupboards doors where the edging has lifted and cracked. We plan to replace all the edging using a iron to melt the glue. Having done a bit of this over the years, it seems the tricky part is getting a nice square end when the strip is cut. I know there are hand tools for applying and finishing the edging, but this a piddly little (unpaid) job.



Any tips on how to get the edging and the trimming perfect?
