That's what would be happened if we treated the keris as amulet / talismanic devices. The Javanese elders had warn us, the Javaneses, by this saying :"Janjine dudu jimat-kemat, ananging agunging Gusti kang pinuji", that means "The promise was not amulet, but to praise The Great Lord" Anyone who understand the keris-making process will know that empu said nothing during the forging, but prayer to God. Keris worth more than amulet.
Without enough knowledges, the bad keris dealers/dukuns in Java will eat you alive, if you looking kerises on them !
Trust no ones, even me
Mr. Purwacarita, if you or your friends really interested in keris and live in Java, you might go to discussion session held by keris' devotee associations. In Jakarta would be the Damar Taji, in Semarang would be the Puri Wiji, and in Jogjakarta would be the Pametri Wiji. IMHO, they are trustworthy associations. You might learn something, but remember, just use your common senses.
best regards
