Thread: HHT Levels?

If all is well at that point, and it always has been, based on the HHT, I go on to strop the blade 100 laps on my SRD Modular Strop with the Bridle leather pad.

Well, if the above is true, your HHT is useless. Yes, a test that always passes is useless by definition. It's only useful if it sometimes passes and sometimes fails, and you take different actions depending on that.

I, like many others, find hair tests useful - sometimes I use them, sometimes I don't, but I hone for fun. However I did pay attention when we learned about measures, so mumbo-jimbo references on ordinal scales don't scare me. Still, ask any pundit or semi-successful politician - nominal scales are the gold standard
