Thanks for all your comments. I'd say the Moro sword makers, at least those in Tugaya in Lanao del Sur, are capable of copying other swords. On my first visit to Tugaya, my Maranao guide jokingly told me about the complaint of someone from Tugaya ... "What's wrong with this government? They say it's bankrupt, that it has no money. But if we help them make money, they get mad at us!" But it appears they don't do it that much today, coz they're good into the metal craft, and the metal coins have very little value these days.
