Origin of the Tombak?

[VANDOO]

I HAVE SEEN THE DAGGERS WITH THE PARMOR SPEAR BLADES REFERRED TO AS TOMBAK, IS IT THE CORRECT NAME OR IS THERE A BETTER NAME FOR THEM

AS TO HOW THE DAGGER MADE USING AN OLD SPEAR BLADE ORIGINATED PERHAPS IT WAS BECAUSE AN OCUPING FORIGN POWER PASSED LAWS FORBIDDING SPEARS BEING CARRIED INTO TOWN. OR IT MAY HAVE COME ABOUT AT A LATER DATE WHEN SPEARS WERE NO LONGER CARRIED AS GUNS WERE BEING USED.
I AM INCLUDING A PICTURE OF THE PHILIPPINE DAGGER SPEAR, THE SHAFT COULD BE REMOVED FROM THE SOCKET IN THE HANDLE AND CARRIED INTO TOWN LEGALLY AS A DAGGER. THERE ARE PICTURES OF 4 TOMBAK DAGGERS AS WELL. AS USUAL THE PICTURES I AM INCLUDING ARE FROM OTHER SOURCES THANKS TO ANY MEMBER WHO MAY HAVE ORIGINALLY POSTED THE PICTURES.
