It's not that you can't chop with it, but that it isnt warranted if you break it while doing so. Like all of H.I.'s product it is built to last. This particular model was originally designed as a replica of an old khukuri as stickfred pointed out. It is meant more as a showpiece. It used to be that all H.I.'s were warranted unconditionally, but over time some unscrupulous buyers were intentionally breaking product to claim warranty and others were claiming warranty on blades that were clearly abused. It was decided that an unconditional warranty was no longer a viable option without costing this small company more than it could afford to absorb and still stay in business. The only other option was to raise the prices more to cover losses, which really wasnt a very good option. It was decided that only the robust actual working khukuri would be warranted for "Field Use" and the others would be "General Use" khukuri to be warranted for lighter usage.I don't get it either. Is the heat treat different (through hardened)? Is it the fullers? That thing is thick, full tang and heavy. If you can't chop with it, what is it's function?Ornamental?
I hope this somewhat helps everyone understand why the changes were made and the reasoning behind it. I'm sure Auntie would've liked to keep things as they were, but unfortunately the economy and cost of replacing khukuri when she really didnt have to, forced the change.
