IT LOOKS LIKE AN EXPERIMENTAL BLADE TO ME. OFTEN PEOPLE EXPERIMENT WHEN THEY ARE LEARNING THEIR TRADE. IN THIS CASE SOMEONE USED A INCOMPLETE AND INFERIOR KERIS BLADE TO EXPERIMENT BY ADDING COPPER INSTEAD OF PARMOR TO THE BLADE CORE. THE COPPER COULD BE WORKED TO MAKE DESIGNS OR DRAGONS AND SUCH BUT IN THIS CASE FORMS A NATURAL BAROQUE PATTERN. ITS WISE TO USE A POOR BLADE THAT CAN'T BE RUINED WHEN YOU START WONDERING WHAT WOULD HAPPEN IF I DID THIS??
IT IS COMMON TO FIND PURE COPPER BLADES MADE INTO SMALL KERIS TYPE BLADES COLD FORGED AND USING STOCK REMOVAL TECKNIQUES. THIS TYPE WOULD FALL INTO THE CATAGORY AS HOME MADE SIMI KERIS DAGGERS. PERHAPS COPPER ALSO IS BELIEVED TO HAVE SOME POWER TO PIERCE THINGS THAT ARE PROTECTED BY MAGIC FROM STEEL BLADES.
