My beef with the H.I. line is because they're slowly becoming modern interpretations of classic knives by smiths who are making them for customers overseas, and thus think that they know what we want.
Let me put it this way. What do you think of when you see a 'tactical katana'? You know, the ones made out of 440C bar stock, hollow ground at the edge, with no tsuba, with a grip wrapped in paracord in a poor imitation of tsukamaki, complete with a high impact kydex sheath?
My first reaction would be to take the 'tactical katana', that modern interpretation of a nihonto, and throw it into a furnace, so I can have the exquisite pleasure of watching it melt into its base components. Nothing comes close to matching the beauty and functionality of a real nihonto, or a japanese-style blade from the likes of Howard Clark, Rick Barrett, and others. To make a modern katana like in the example above is to sacrifice too much quality for ease of manufacture.
Now, I'm NOT saying that H.I. khuks are as bad as my 'tactical katana'. I'm just saying that certain aspects of the traditional khukuri were sacrificed in the name of production speed. Brass is certainly easier to work than steel, and is more plentiful, and cheaper to boot. Angled blade profiles are easier to produce than the continuously curved profiles of classic khuks. Thicker steel blades ARE easier to produce than thinner steel blades - Bura had once said that he was the ONLY kami who knew how to make a thin blade without screwing it up, so it seems to me that a thinner blade is harder to achieve than a thick blade, which leaves more room for error.
