[Histonet] tungsten knives for cryostat

[Kim Merriam]

Hi All,

I am in need of some disposable tunsten knives for my cryostat.  It currently 
has a low-profile blade holder on it, but I can't seem to find any disposable 
tungsten knives that are low-profile.  Does anyone know if they are available?

If not, I can just buy some high-profile ones and get a new adaptor for my knife 
holder.  What company makes the best tungsten knives?

Thanks,
Kim
