Re: celloidin and tungsten carbide knives


tried it, but on my microtome the blade holder did not seem to hold the
blades well enough to keep it from chattering when hitting the much harder
celloidin, i think it was more a problem with the strength of the holder
than the blade itself.  for plastic or celloidin microtomy in my hands
disposable blade systems have not been satisfactory, i use 6 in. tungsten
carbide blades that are resharpened.
