Dear Russ,
Its been years since I used a knife that had to be sharpened. My last
cryostat was a Leica CM 1800, with a disposable knife holder. I used
'Sturkey' gold plated high profile blades, they sectioned through mouse
femurs at 5-10 um very nicely. I was even able to section through whole
mouse (ribs, pelvis etc) at 60 um without too much stress (cryotape is a
life saver here). I found I needed to move (or change) the knive after
about 5-6 sections.
I admit the initial conversion to disposables from solid knives is a bit
expensive if you don't have an appropriate holder, but in the long run
there are many savings.
Regards
Rob W.
