[Histonet] How to keep cryostating without getting frostbite?

I cut little rectangular pieces of styrofoam from any of the cartons 
that are shipped in with cold or frozen items and "glue" them to each 
side of the knife holder with OCT. This provides a great area to rest 
my hands while having to manipulate a frozen section. The styrofoam 
doesn't get cold and it is a comfty place to put your hands and also 
a slide if you have to pick up multiple sections on one slide. The 
tissue and OCT doesn't thaw or the slide doesn't get too cold for 
another section to attach.
This excellent piece of advice came from Gayle Callis - thank you 
again Gayle!!!

PS: When I want to clean out the cryostat I just turn it off and take 
out the knife holder and when the OCT warms up the styrofoam comes 
off and can be reattached when the cryostat is all clean and ready to 
be turned back on.
I was reading where somebody suggested something to a manufacturer 
and the idea was not readily accepted and I likewise have made what I 
thought were excellent suggestions and was met with similar responses 
- this styrofoam thing was just one of them.
