Another vote for Kailash. I haven't had the chance to have one in hand, but they have some pretty impressive testing videos. Like, chopping rebar without damage, chopping through a nail with no damage, chopping buffalo horn. Interesting back story on the company, too. It was formed by kamis leaving other khukuri manufacturers due to dissatisfaction with quality standards, pay, and working conditions, under the guidance of a fellow from Australia who had several designs produced by one of the other khukuri manufacturers and got aggravated with them. He had brought modern heat treatment methods with him, and that manufacturer was just unwilling to put in the extra effort it took to produce the higher quality blades on a regular basis. I honestly don't even remember which company it was, but the attitude was that if someone broke a khukuri, they'd just make another one, rather than make some changes and improve their overall product.
Kailash is now producing designs from several American custom knife makers. No, I'm not one of 'em.
