A Richard Allen MICROM microtomy specialist gave hints that Richard Allen 
Edge Rite blades high profile are approx 11 degrees, and low profile may 
need to be a bit more at 12 degrees.

However, blades from different manufacturers may have differences, although 
small and if one has difficulty with angles using any given blade, start at 
around 11 degrees or so (10 degrees would work too) and increase or 
decrease the angle in very tiny increments until you have optimal cutting 
for the blades one purchased.  Differents lots of blades from any one 
manufacturer can have differences too,  so learning to adjust angles is 
critical for good microtomy.

We set ours at 10, put that is personal preference.
