KERIS WOODWORKING TOOLS AND TECKNIQUE

[VANDOO]

A PICTURE OF THE RARE NEEDLE KERIS SCABBARD FROM BALI. JUST KIDDING.
WHAT SORT OF TOOLS AND TECKNIQUE WOULD BE USED AT THIS POINT TO FIT THIS SCABBARD TO A KERIS BLADE? TO FIT A PESKI INTO A HANDLE IS FAIRLY STRAIGHT FORWARD JUST DRILL A HOLE A LITTLE BIGGER AND DEEPER THAN THE PESKI IN THE HANDLE.
TO FIT A BLADE ONE WOULD HAVE TO WORK FROM A SMALL HOLE SUCH AS IS SHOWN HERE TO ONE CONFORMING TO THE EXACT SHAPE OF THE BLADE AND FITTING SNUG BUT NOT TOO TIGHT. DOES ANYONE HAVE PICTURES OF THE SPECIALIZED TOOLS AND METHODS USED.?
THE SCABBARD PICTURED IS FOR EVERYDAY USE IN BALI OF A FORM CALLED A WALIKAT. CORRECT ME IF I AM WRONG. I HAVE SEEN THESE CARVED FROM ONE PIECE OF WOOD AND ALSO WITH IVORY AND OTHER WOODS USED AS INLAY OR GLUED TOGETHER IN A COMPOSIT FORM. WHAT IS THE OLD TRADITIONAL WAY OF MAKEING THESE?
IS THIS FORM SCABBARD ONLY FOUND IN BALI OR PERHAPS MORE WIDESPREAD?
IF CARVED FROM ONE PIECE OF WOOD WOULD THE TOP PART STILL BE CALLED WRANGKA AND THE BOTTOM GANDAR?
