Well we guess that settles the debate concerning whether a straight edge can be sharpened to the level of a DE razor blade. In explanation of how the PT50B with 5 grams of resolution calculates BESS numbers it goes like this; anything calculated at/including 7.4 grams down to 2.5 grams will be displayed as 5 grams. Anything above/including 7.5 grams up to/including 12.4 grams will be displayed as 10 grams. In theory, the impossible, a reading of "0", would be possible with a PT50B and to a much lesser extent a PT50A due to this rounding function. In fact, a PT50C with 25 grams of resolution might have given these YouTubers a reading of "0" with their straight edge razor. Having offered up this explanation, it is misleading because, in reality, all values that fall outside (or inside however you choose to look at it) the resolution of the instrument are just noise.
In any event, these guys did offer up a very entertaining demonstration of the capabilities of a PT50B. We do wish that they would take better advantage of the knife fulcrum but, in fact, when working with edges that are very sharp (under 150) use of the knife fulcrum becomes less critical. Thanks to SHARPCO for bringing this to the Exchange.
