As Khukris go, the Killa Zilla can hold its own with my HIs, but none of mine are as big and heavy as the KZ. I question even the need for the super thick HI Khuks. I know, I have angered both HI and Busse lovers by now, but those thinner LTC Khuks from Cold Steel chop better. My Condor golok can kick some khukri butt. It's a chopping machine. I just don't think I need any 38 ounce half inch thick knives, as impressive as they are. I have an axe.
The LTC also beats my HI khukris as was demonstrated by my old chopoff. The FBM did as well. I think the most desirable HI users are villagers in the 17", 25oz range, but their products offer more to the khukri freaks than just chopping performance. The same thing goes for INFI hogs. It's something about mystique, be it magic, chemistry, beauty, or craftsmanship.
The LTC ignores everything for the sake of pure chopping excellence. Think I'll go play with mine, now.
