i use a cryostat to section my embryos and every so often the blade gets 
sent out to be sharpened.  when we get the blade back it is SO sharp that 
the tissue immediately curls before we can get it on a slide.  we do use an 
anti-roll plate.  recently we have been using old embryos or straight frozen 
cryo matrix to dull the blade enough to stop the curling.  this however, 
takes a while.  does anyone have any suggestions on how to dull the blade 
once it's freshly sharpened?
