Yeah I might leave it alone then, or perhaps try lime which is close to calamansee in the Philippines.

I disagree with Kai however, especially if the etch is in browns, yellows, and greys like when I etch. I will admit, most of the time the blade is in the greys, so I then leave it alone without further etch and use baking soda on the areas etched.

If you do use ferrous chloride, dilute it with distilled water, or else the reaction won't be clean.

Again, I have an early Sulu-Tawi Tawi kris wavy blade (1700s) without a twistcore or any other lamination (that I can see).
