I have Shapton up to 16K. This is something I'd like to try. Now I have an excuse to be able to devote uninterrupted time down in "Razorville" as my wife calls it (the basement). Unfortunately I don't see myself getting this luxury for a week or two.

I love the HHT and actually use it every day not only because it's one of the many tests for sharpness, but also because it does have an exciting essence of parlor trick to it and I'm the amused audience. Every morning after stropping and before shaving the razor gets an HHT if anything else, then for fun. I have ultra fine blondish hair and until this year was convinced that even the sharpest razors or any razor couldn't sever my hair. Wrong. Ultra keen blades "ping" by hair now. I got better at honing.

My sharpest razor at this time is a DD Dwarf and I shave with it often. Easily passes the HHT every time.

I've heard it said that an ultra sharp razor can have an edge so sharp and so polished that it does not pass the HHT. I have trouble accepting that.

I saw Randy Tuttle earlier this year and he graciously showed me some of his wonderful collection. If I recall, he had a Hess Hair Milk razor that he said was far and away his SHARPEST razor he owned. I'll PM him and ask him if it passes the HHT. I've never owned or used a Feather blade. For those that have, do those blades pass the HHT?
