I decided to hop past the rocker and head for heady shores a big proper microtome, with replacable baldes.
On another odd note I discovered there is a disposapal knife holder for the cambridge rocker. Its just it costs £473.
Its from pfm medical. In the unlikely event anyone from the forum wants one I can provide a contact email to source this difficult to source item.
I have not tried it but the source is exceptionally knowledagble about microtomes and works as a consultant for pfm.
Anyway. Thanks to John B that gave me a little push in this direction.
It should be with me soon ish. This being the last detail to tie up in the transaction.
