Thanks for the kind words it really helps and all the back ground info. I now understand the repeated resharped or ground edge profile.
When it arrived I cut open the parcel and held it with a sense triumph. Then straight to where I clean them. Cleaning with my heart pounding and enthusiasm enough to perspire

, behold!!
DOUBT 
I am sure I am not alone here. Like they say the bigger they come the harder they fall.
So thanks, I will keep it for the time being then I might waft it under a certain collectors nose. I could put a silver rivet in if you think it would help?
