Very interesting topic and video.
Mike's comment about the sensitivity range of the PT50-B says a lot about his knowledge of his products and, just as important, his integrity. Mike is acknowledging a fact of precision measurement; every measurement tool is designed for a particular range of accuracy. Numbers are only meaningful when the user knows the context.
For those who want to learn more about measurement and who are not afraid of a readable book of many pages, Inspection and Gaging is a fascinating read. It was first written to bring new factory recruits up to speed during WWII. I enjoyed reading it and have found its information valuable. Here is a link:

My everyday tester is the original PT-50. Its accuracy range more than meets my needs. If it had been available at the time, I would have purchased the top of the line PT-50A. The EOU line up of testers follows industry practice of having tools for the worker on the factory floor; inspection tools for product inspection and periodic checking of the floor tools; and laboratory tools for the most critical work. For the home cook, the PT-50C is the perfect tool. It is compact, easy to use, relatively inexpensive, and has more than enough accuracy. The PT-50B is the ideal tool for the sharpener. It delivers noticeably higher precision than the C version at reasonable cost. When we get into discussing the "KnifeGrinders" range, we are in the domain of the PT-50A range. I do not feel that I need the PT-50A to participate in the discussion, however, if I was regularly posting with high accuracy BESS readings, I would upgrade.
I found the video quite interesting, however, working that way would soon bankrupt a farmers market sharpener. I am fascinated with pushing back the sharpness frontier, however, I am more of a Grepper sharpener. I want very sharp edges consistently produced in a time efficient manner. My kitchen knives just need to work.
Good topic; thanks for posting it.

ps I like the 600 BESS "child safe" designation.
