here is a ref to the Kukri :
https://en.wikipedia.org/wiki/Kukri
its for slitting throats
even though Wiki dances around this.
note the notch :
""" Kukri blades usually have a notch (karda, kauda, kaudi, kaura, or cho) at the base of the blade. Various reasons are given for this, both practical and ceremonial: that it makes blood and sap drop off the blade rather than running onto the handle ''
lots of blood when you slit a throat.
the two little knives that you carry w the Kukri are to eat what you've just slitted , after suitable cooking of course.
also in the article :
"""" Mina's narrative describes his throat being sliced through by Jonathan Harker's kukri ""
just a quick pull and slice will do it ! no jabbing involved.
from behind of course !
