Go to Thomas Scientific and look at the Thomas-Stadie-Riggs tissue slicer.  
The plastic slicer clamps the tissue for stable hold during slicing with
longer/sharp blade in a blade holder.  A simple device and you do not have
to prefix the tissue before slicing.    

We used these to slice brain and other large tissue samples.  If you have
their catalog, it is on page 1134 under microtome accessories. Website is
