Those two are acid trips I don't want to take!
When it comes to etching blades, I do feel that when in doubt, less is more (and I do a lot of etching).
And in the case of my Balinese keris, I have left it alone (thank you forumites for your advise). If it ain't broke, don't break it anymore (especially in my case). On the other hand, nice job Smashy!
