I know all of HI's Khukuris are handmade by a variety of skilled Kami...and thus all measurements are approximate as would be expected. Am I to assume that when a length is quoted it is the overall length of the knife? If so is that measured in a straight line from the pommel to the tip or curving along the spine...with a tape measure? I am zeroing in on the BAS, the CAK, the WWII, or the M43. Also, what is the length of the M43? It looks bigger than the others. Is it? I am also trying to decide between the tank-build 1/2 inch models vs the lighter models like the BAS. I have a lot of knives so I don't need a knife to do it all. If I carried a Khukuri into the woods or the desert, I'd have other knives along as well (at least a nice folder if not a Mora or something too). Not a big hiker...bad feet...so weight is not really a consideration within reason.
