Bill Martino used to purchase Khukuris from the same factory as Khukuri House and Ghurka House. Ghurka House then got in on the business and that must have driven Bill nuts. Incidentally I have the Ghurka House video on the making of khukuri's. A bunch of craftsman were involved in making a khukuri. The buyers in the Ghurka House video are the men operating Khukuri House. I have a couple of early HIs, and they are definitely from the same group of workman. Bill had someone pick the best out of that factory and charged $175.00 for them.
Later HI khukuris are excellent as a class, but I really dont know if it is a separate group of people making them. But it is likely. Considering the first Khukuri House khukuris were like $5.00 or $7.50, Bill was probably able to buy a city of knife makers based on the profit he made on one Khukuri.
Bill maintained that he was extra benevolent to his knife makers, but he never revealed how much of each sale was going back to Nepal. Without an accounting of his books, I always considered his benevolence is an unsubstantiated claim, designed to make his American customers feel extra good about spending extra money.
