Re: [ccp4bb]: Cryocrystallography Tools?

Dear all,

 Everybody who has dealt with crystals, specially during beamline time, knows what is NOT to have a good set of tools to gently
deal with crystals resulting from months of hard work.
 Since Mr Kostreva is asking something related, I think it's a good time to announce that at the Brazilian Synchrotron
Laboratory we had the opportunity to design and build microtools for protein crystals, which fit better to crystals dimensions
than Hampton's tools, for instance. They are not in final version yet, for we have not fully tested them. Its usefullness will
highly depend on design sugestions as well. I attach one picture of a loop built here.

Best regards,
Jose Brandao
