Welcome to the Forum!
I agree with what everybody else has said. I haven't seen a GH khukuri, but I have seen one of the Gorkha issue ones, which are also made by Khukuri House. They are good knives, but IMO, not up to par with an H.I. There seem to be some other differences besides finish, too. It seems like the GH khuks are consistently lighter than the HI's. This is because they have slightly thinner blades, at least I know the knife I looked at had a slightly thinner blade than an my HI BAS. They also aren't hardened as well. GH khuks tend to beabout 54 to 57 rc; HI's are consistently at least 58 rc, with some kamis (particularly Bura, I think) tempering knives up to 62 rc. GH's often also have smaller handles than HI's. All in all these are really only minor differences, but they add up, and I think the HI is just a better khukuri.
