Hi Foaming Mug,
I don't know which one you are but I met one of you (the older one, without the tatoos) on Sunday after lunch at the workshop.
Your hot cut hardy looks good but since we are all trying to get better and you asked, I'll see if I can give some helpful suggestions.
There needs to be a fuller indentation at the top of the shaft 90 degrees to the shaft. I can't tell if you have one but on Brian's I measured about 1/2 inch between sides (thickness). Then I would work more on the end and flatten the "hills and valleys". When your flatter is almost getting flush with the bottom of the horizontal fuller mark, start a taper towards the end until you end up with around 1/8" or slightly thicker edge. This will enable you to grind with the appropriate angle and function properly.
Hope that made sense.
Bill
