[Histonet] Duraedge (Black) help

[Hans B Snyder]

Hello All,

I recently switched from Duraedge (red) to Duraedge (black) blades.  This
has caused cutting problems on 1 microtome, our Leica RM 2235 microtome but
no others.  The sections are now thick and thin, compressed or lengthwise
ribbon splits.

I tried changing the blade holder angle, 6 forward and 6 back positions
with no luck.  After trying 12 different knife angles with no luck, I had
someone PM it and it's still not working. The original red blades still
work in the microtome and I don't understand how only 1 microtome does not
work with these blades.  Instead of buying a whole new case of red blades
just for this 1 microtome, I thought you might have some insight that could
help.

What should I do?

Thank you
