This stitch is a TAST stitch!
Sharon Boggon of Pintangle started the online course of embroidery stitches, TAST (Take A Stitch Tuesday) in 2007.
I first took part in TAST in 2012 and worked the stitches that followed regularly until 2014 when I had a complete set of stitches, or so I thought. This stitch was not included.
After some research I noticed that there were a few TAST stitches from earlier seasons that I had missed, so those were added. This stitch was not one of them.
Thanks to my readers I found out that what I call Sword Edging Stitch and gave Sunday Stitch School number 53, was introduced in 2010 as TAST Stitch #17 under the name Sword Stitch. I totally missed that!
Anyway, I just love this stitch. It is easy and quick and I think it can be used in many ways.
Here is my homework:

and on the orange scribble cloth I worked three flowers:
To spice them up a bit I added a few Colonial Knots in the centre and made a stem of Stem Stitch.
This stitch could also be used to illustrate fireworks, a picket fence, crosses and of course, swords!
