How effective is cork for removing fine burrs, Edge On Up Bess Test PT50B 

Normally for final burr removal I prefer to use a nice firm (bare) veg tan leather, in this video I use a wine cork for the final de-burring. I sharpened the 8" chef's knife on Shapton Pro 1k stone and then cleaned up the edge on a strop (smooth side veg tan) that is loaded with 0.3mic Cr2O3 abrasive. I take two base measurements on the Edge On Up PT50B and then three more afterwards to see if there is any improvement.
I examined the final edge under magnification and also ran it across my thumbnail, apex appeared and also felt very clean/smooth after using the cork. When de-burring straight off Shapton 1k it appears to rip the burr off or portions of the burr leaving a very rough apex both using the nail test and under magnification.
