I had 4 knives directly from Randall,
none was as sharp as a razor.
If I'm not mistaken, the sharpening in the store occurs
manually on the Norton 313 system
(if I remember correctly the photos that were
somewhere placed here).
They are just sharp enough to work.
Yes, I remember on the model the triathlete was not completely
removed burr.
Photos of the cutting edge, an increase of 70 times,
The first photo - the presence of a burr after India fine,
second photo after Washita,
the third photo after black Arkansas.
grinding time ~ 6 hours
To get a razor, it is necessary to sharpen carefully
on smaller and smallest stones (1~3 micrometer),
it takes a very long time.
Modern synthetic materials, by the way,
it is better to cut more roughly sharpened blades,
this was confirmed in the process of working with
electrical cables (cutting edge in winter, when the shell
of cable is frozen, glides).
I think that Randall is just making the sharpening,
which is equally suitable for both synthetic
and natural materials. Next, the user himself
sharpen knives for his needs.
I would compare the factory sharpening with
the tires of a car. When you buy a new car in the cabin,
you have a choice of tires, it is usually one
of several standard options, but often there is no choice
and there are only one types tires.
Next you have to buy those tires that you need.
If you drive on snow and ice, then you need tires
with spikes, if you drive through swamps, then you need
tires with powerful grippers and self-cleaning ones.
I would like to give interesting information about
sharpening, if there is no objection (if not, I will delete):

This is not advertising, just the words of the master,
which coincide with my practice of use
(but he talks more professionally and accurately).
