Thanks Mark and Andrew
The 'spine' side of the tip is actually quite sharp ...with no evidence of any recent 'honing' , the patination is the same as the blade. I am not saying that this tip was not the result of a 'break' but, I think the design would allow cutting strikes on the 'back stroke' ...surely a surprise for an opponent as the 'normal' tip profiles would not allow this ?
Re-checking the spine I have discovered that the last 3" before the tip is also quite sharp, as sharp as the edge is presently (Although sharp the blade it is not 'razor' sharp , but as I said before there is no evidence of any recent sharpening and has been 'untouched' for a long time.) This attribute also suggests it could 'slash' on the back stroke.
The handle length is quite long in comparison to the blade length ...is this normal....Thank you
Kind Regards David
