Welcome Irezumi
Cybrok is exactly right. HI is run here stateside by Yangdu Martino, the widow of the late, great Uncle Bill Martino. She is a native of Nepal and receives shipments from her father's blade shop which she sells out of her home in Reno, NV.
The prices are a little higher. However, given the high shipping cost of the "direct" manufactures, it generally turns out that the prices are nearly identical. HI is a business founded on ethics. It attracts some of the best kamis (bladesmiths) in the region because it pays well and provides medical coverage. The QC of HI is second to none. Blades are inspected (as well as blessed) before they are shipped to Reno. Once there, Yangdu's eagle eye looks them over for any damage that may have happened in transit. Anything that is not perfect, is sold as a blem (one-off) here on this forum at a deep discount.
Finally, HI has a no-nonsense lifetime warranty on their blades for the original buyer. If the blade or handle ever fails on you, and you weren't abusing it (basically short of chopping up tank armor) they will replace it.
What it boils down to is: a great blade made by the most skilled hands, a company that actually values and does not exploit their employees, and fantastic quality control with a very fair and honorable saleswoman.
Like Cybrok said, take a look at the FAQ. HI has a fascinating history

Once again, welcome.
