We do not use the Shurmark system,  but the system we use is that all the cases 
for the day are listed on what we call a check-list. On average we have about 50 
cases daily, giving us about 100 blocks. Then the total number of blocks is 
divided according to the number of microtomists. The number is then rounded up 
so that each microtomist has complete cases and no particular case is divided 
between two microtomists. In this way we know exactly who cut each case and 
initials are not required. 
I hope this helps, it sure works for us.
