Strange razors!!!

I went to York Antique & Collectable Market on Saturday. A guy had a box of about 30 razors in varying condition, the first one I opened was a strange shape ( As the picture) but with no hone wear. I thought this was a style I hadn’t seen before! There were some with real dyer home made scales on
( would like to have shown them but he wanted £2.00 each) as I got through them I found a couple with really bad hone wear, A hollow ground turned into a wedge! Then there was a “Gong” razor shaped like the picture and I realised that this was done by sharpening! The guy said the razors were from a barber?? But I cant see how you could sharpen a razor to this shape without any hone wear. Has anyone any ideas??
The picture has been edited to look like the razors the guy was selling.
