Bill,
Thanks for the answer. I have a couple of further questions.
Are the "clip-point" or the spike sharpened, too?
Is the spike decorative, or does it give some tactical advantage?
Also, what initially confused me about which side was sharp was the direction of the handle. Most kampilan seem to have the "jaws" of the handle flared toward the sharp edge, which makes sense to me ergonomically. Yours has the jaws facing the spine, which seems (no offense) backward to me.
I guess it doesn't make any difference which way the jaws are facing?
