Today I saw a video which demonstrated a new (to me) way of assessing sharpness. He uses the banding from off brand plastic soda bottles. He asserts that the name brands like Coke and Pepsi are a little thicker and easier to cut.
Today I was shopping and I got a bottle of Ginger Ale. I tried cutting the label and I must agree with the statement. In my brief test it was more sensitive to sharpness than magazine paper and newsprint. I keep reminding myself to look for cigarette papers but so far I have forgotten.
If anyone has a Bess tester it would be interesting to know the highest value that will easily cut the label.

Cool thanks.
You might be able to compare to some other tests in that knifegrinder's chart (http://knifegrinders.com.au/Manuals/Sharpness_Chart.pdf), to get an idea?
(Wonder how it would compare to cutting something like the thin plastic in grocery store bags)? ???
John,
I watched the video. Interesting idea, just be careful not to injest any of the contents of the bottles. :)
Here is a testing you tube by our own Steve Bottorff:
