Help with Identification please

[A. G. Maisey]

This is a pic of a Bali blade that has been in pineapple juice for about a week. It has been taken out most days and scrubbed with an old toothbrush, the hard bits of rust have been picked off with an old file ground to a point, it has been scrubbed with sink cleaner, steel wool, and a scotchbrite pad.

The pic was taken today after it had been removed from the pineapple juice and just rinsed off with water.

As you can see, the pamor has started to come up, and for some people this would be an adequate finish. I will give it a couple more days of soaking, then I'll hit with lime juice and arsenic, and the end result will be that the ferric material will be a lot darker, however, if you don't like handling arsenic, or cannot obtain it, this finish would be a whole lot better than the red-rust all-over finish it had before I started.

Ignore the blade shape, its distorted because I took it at an angle so the pamor could be seen.
