I shaved with the touched up blade tonight & the result was a smooth &very comfortable shave .
In fact I have owned three of these razors in the past & none of them gave a decent shave ,but I my have been too hasty when I passed them on as I have improved my honing ability since then & I am hanging onto this blade as I believe I have just scatched the surface as to the capability to this type of grind.
I will keep posting as I improve my technique with this razor.
Cheers Paul
