There are many roads to sharpness, everything from sandpaper to diamond stones to natural stones. But, once we get to the end of our mating dace with the stones, how do we know we are sharp?
I've seen several ways of testing for a zero radius. The thumb nail test, paper cutting tests, shaving ones body hair, looking at the blade under light, shaving pine end grain, and even shaving skin off of the thumb(which I don't recommend).
Out of all those tests which one provides the best example of sharpness? Well, I don't know, at least not yet. I have thought about this for a while and always wanted to test the different methods, not only with one blade, but with several blades at different levels of "sharpness". The closest I can get to a scientific test.
To accurately report on these different tests I would like to know what the majority of people do to test sharpness. So, check out the poll and let me know. I have a feeling the results of the final test (which will be on video) will be quite surprising. Hopefully.
