The "sticky" quality of the TPT, for me, is only accurate at the bevel-setting stage. Once I have a finished edge, one that can pass the HHT and shave well, the TPT reveals nothing: it feels like a dull blade. I don't doubt it's cutting skin, there just is no "sticky," "caramel-like," or whatever feel to it. I posted about this some time ago: some agreed with my experience, others did not. You must establish your own frame of reference.
