Yes, remember the Bancha?
On khukri size, off the top of my head I'd guess more like 14 to 15 inches and about 16 to 20 ounces, depending on the region. They import steel from Indian junkyards, so the cost for heavier weights of steel is prohibitive for the poorer folk.
There was an article on going into Kham where one of the guys wanted a khuk like the yak boy had. They took him to buy a spring to make the khuk from, then a day's journey on foot to a village kami, then waiting for the kami to make it.
The idea ( IIRC ) is that a blade is forever, a handle is not. The average village khuk has a partial tang set by heating and burning the tang into the wood, followed by adding laha ( local cutler's resin ) and maybe some plastic, reheating the tang and inserting a last time for permanent set.
Remember that khuk's are hardened and drawn at the same time by letting residual heat flow back into the edge area from the spine after using water poured over the edge. Thus the thinnest part stays hardened, the somewhat thicker area behind the edge is draw to a lower hardness, and the spine and tang stay dead soft.
Eventually, the khuk will be sharpened past the treated area. By then it's usually time for another handle anyway. So the khuk goes back to the kami, gets fitted with a new handle ( or if it's still good, the tang gets reseated with a bit more laha ) and the edge may be rehardened as is or hammered thinner.
Uncle has told of seeing khuks that had to be originally thick, used down to next thing to a fish fillet knife. Waste not want not doesn't begin to cover it.
