My thoughts:
- It isn't huge.
- That isn't a barber's notch, surely the tip has snapped off? The point is deadly.
- The writing on the tang - is it the correct font? Looks like it would be easy to stamp onto a fake.
- The blade edge looks like it was sharpened recently (badly) yet the spine looks untouched. So how was it "sharpened"?
- What is that vice in the background? What horrors have been inflicted on this poor blade?
I could be wrong about some of these things. But I would have avoided this.
