"The khukuri handle seems to me to be designed so that the butt cap will slide past the heel of your hand when held properly. It's a foriegn concept to us in the western world"--Yvsa
I'm with Yvsa on this kind of "side" grip. I call it the sword grip, because essentially that is what it is. There are certain ways to hold european swords that involve this same grip. If you understand the grip, then all the bulky looking pommels and buttcaps on blades suddenly make sense. Moost viking swords, for example, have a small grip with a huge flat pommel or crossbar that feels terrible if you hold it like a baseball bat. If you hold it correctly, the pommel actually stabilises the hand for accurate and forceful swinging. The pommel IS the guide.
