Dear Dirk and all Meteorite Fans, As an iformation, I just cut for the first time some of our CO3 (Acfer 333) with a 300µm thick blade, and polished them afterwards in order to remove as well as possible the blade's scratches. The total loss has been about 25%, based on an original fragment weighing 92g. This meteorite is quite porous and fragile (less than our Acfer 331 - CM2, but not that far...). Just my 2 cents,
