I am trying to locate razor blade holders for American Optic Microtomes
model 820.
This razor blade holder clamps into where the stainless steel blade would
rest.  The holder looks similar to a stainless blade but has an attachment
sight in the center for a razor blade.  Any information as to where these
could be located would be greatly appreciated.  This equipment is used in
microtechniques classes.

Thanks for your help,
Sincerely,
