John Minnery's premise is that the objective of the attack should be to stop the flow of oxygen to the brain.
From Minnery, Vol I:
"Hacking weapons are very effective and include axes, hatchets, mattocks, broad swords, cleavers, machetes, etc.
The cief concern with these weapons is that they be sharp as possible and that they have a fair weight.
...
When used as a weapon, the tendency to hack and hack must be discouraged. Lopping off arms and legs and attacking the face is unnecessary and only adds to the disorder and confusion. What is desired is a one-two approach. One, a downing or knock-out blow. Two, severing the head.
...
Although the neck is a prime target, the skull can be bisected. The chest cavity can also be penetrated to the heart with these weapons resulting in mortal wounds."
===============================================
Note:
The Gurkhas have a reputation for using khukuries to either remove the head, or bisect the skull (sometimes all the way down to the naval). Virtually, every historical refence on Gurkhas will include a few of these stories. Argentinian troops who surrendered in mass during the Falklands War, gave the reputation of the Gurkhas (especially their khukuries), as one of the reasons for their surrender.
The best khukuri would be which ever one you are most familiar with, although we can observe that the issued military khukuries were about the size of the HI BAS, and WWII models and somewhat lighter. Anyone who has been hunting knows that chopping through the rib cage is not an easy task. Calcium is a mineral and plenty of hunting knives have been destroyed in the attempt (the halfmoons on my Gerber LMF were up to 1/4" deep and 1" across when I tried it). So it would be important to go with something that has significant edge strength.
