[meteorite-list] Sawing

[wrecks463]

Hello People,     Can anybody give me some hints on a good way to saw up an iron meteorite? I spent 2 hours hackin away at a campo del rusto with little luck. Is a carbide tipped blade the way to go here? I noticed that it would saw good then hit a hard spot,then saw,then stop when it hit a spot that just stopped all together. I tested the rockwell hardness and it came out to less than 20 (that must of been a soft place). I figured 30 minutes per cut...Ha! Any advice would be greatly apprieciated.                              Thanks,                                      Rex
