Yes, but why did such teeny tiny imperfections survive the stropping process?
Verhoeven got lots of cr*p around here for his claim that leather stropping didn't remove the burrs, with guys claiming that this proved he either (a) didn't know how to use an EM or (b) didn't know how to strop. Here we have another case where stropping (surface unknown) did not remove the burrs from the edge.
So are these really burrs left over from honing and surviving multiple shaves and stropping sessions, or are they actually caused by the stropping itself - e.g. are these caused by plastic flow of the steel against the strop?
Inquiring minds want to know...
