A new level of sharpness achieved!

And don't forget the cutting board!
My quick test on the PT50 shows that 20 slices on a plastic, glass, marble and bamboo cutting boards reduce sharpness by 3 times, e.g. from 90 BESS to 270 BESS.

Of all plastic cutting boards, only the Japanese polyvinyl acetate Yoshihiro Hi-Soft cutting board doesn't dull the edge, but it costs a little fortune.
A good end grain wooden cutting board is the best, I recommend Acacia here in Australia.

any testing using HDPE or PP plastic boards or edge grain wood boards?  
end grain boards are a chore to make and crazy expensive to buy.  
wish you here in US, would like you to sharpen one of my knives.
