It may be better to do the sectioning of these samples using a tungsten 
carbide tipped knife , d profile should work.  A regular steel c profile 
knife will not cut through undecalcified bones very well.  It take the 
extremely hard TC knife for this purpose.  Since Historesin Plus is GMA - 
you may want to enter into some discussion about this plastic and 
sectioning with "Patsy Ruegg"  as she has experience 
using this kind of knife with undecalcified bone embedded in GMA.
