[meteorite-list] Rock saw blades

[scotia143]

Hello I have two questions that I am hoping someone can help with.  The first is quite easy.  I am trying to locate a six inch diamond blade that is as thin as possible but still stable.      The second question may be more difficult.  I recently recieved a gift that I am having trouble identifying.  It is a tin can that was used as a field container to store meteorite samples. It was the property of J. Lawrence Smith. It was used in the field to store a find that is labeled " Broadhead Missouri   Met."  I am afraid that I can't find that name and I really don't know that much about J. Lawrence Smith. Any help would be greatly appreciated.  I like this can and would like to know more about it.   Thanks in advance Darren Geswell
