Same steel... probably. Same quality? Eh - debatable. Ethical business model, care for their workers and dedication to their customers? Sorry - no way anyone is beating HI there. Those other places might be cheaper and produce kukris of fair quality, but they don't have the sort of background that HI does. HI pays their workers a very good wage so that they can support themselves and put their kids through school. They back their products with a lifetime warranty because the kamis take pride in their work and HI wants their customers fully satisfied.
Those "other" manufacturers also ship directly from Nepal, which means an added ~$40 to shipping costs and a 4-6 week wait. If you have any issues with your product, you're dealing with someone overseas and even if you get cleared for warranty service, that means $40 for shipping it back. With HI, you get to deal with Aunty Yangdu who lives in Nevada - if you have any sort of issue with your kukri, she'll do everything in her power to ensure that you end up happy with your purchase. Honestly, she is one of the most pleasant people you will ever have the pleasure of dealing with :thumbup: HI also has this forum built around the business. It's a great community with amazing, helpful people and a wealth of knowledge.
Ultimately, it's your call as to who you go with. All I can really say is that I went with HI when I faced the same decision a year or two back... I'm completely satisfied with my decision: I feel great about supporting such an awesome company, love the products, love the community, and have received nothing but outstanding service.
