Tombak Opinions Wanted

[Nagawarrior]

Thank you for your input here Alan. I didn't want to print your full reply to me without your permission so I just thanked you when I started this thread. I hope I haven't committed a faux pas.
I still would like to know where I can obtain some of the arsenic trioxide for staining here in California. Can any one help with that? I find great pleasure in hands on care of items in my collection and really want to try to stain myself. I probably wouldn't start with this Tombak. Rather as suggested, start with a low grade Keris I have so I may learn. I have used the method suggested by Alan in the past, but had to resort to Radio Shack etchant for the acid. This does not produce the pleasing look I want. It works well on other swords I might say.
Thanks to all here for your replies. They are much appreciated
