Jens, you beat me to it!
Yes, Rasdan, by all means, have some sort of chemical analysis done. It's for more than our curiosity--it might also be useful to the empu who does the work, to know what's in the meteorite you bring him before he starts working on it. It will be interesting to see how the pamor develops in such a blade.
Nechesh, thanks for discussing Prof. Piakowski's work. Now, if some chemist in the group will explain how arsenic binds differentially to phosphorus to produce the light and dark pamor bands, I'll be happy
