There are many levels of sharp as there are many levels of shave ready. The shave is the final test and the only one that matters unless all you are going to do with the razor is the HHT. The sharpest edge is not always the preferred edge to shave with. It comes down to personal preference.

For me, I aim to pop arm hairs one at a time at several points along the edge off the lowest grit hone I am using. From there I am just polishing the bevel and refining the edge. I test on arm hairs after each hone. The final test is to get CarrieM to test on her baby fine leg hair. If it shaves them dry, w/o stropping and w/o tugging the blade is ready. At that point it will perform the HHT w/o fail almost every time, w/o stropping. The HHT is entertaining but I don't use it for testing shave ready. As a note, CarrieM prefers her edges straight off the coti, used as a finisher, water only. This produces a sharp edge and smooth shave but is a little short of shaving skin off for skin graphs.

The final test is the shave. No if, and or buts and is a personal evaluation, not a science.

Good luck!
