Nismo,
Welcome to the forums.
The khukuri is first and foremost a traditional utility knife used in and around Nepal. It was made famous by its association with Ghurka mercenaries which have been operating under British and Indian authority for well over 150 years. It is very similar to the ancient Kopis and Facalta swords, and so represents a style of knife/sword whith a history of some 3000 years.
When used as a weapon the khukuri can be quite fearsome. There are numerous well documented reports of individual Ghurkas killing bears, and lions in self defense, and larger examples were used (and are) used in religious ceremonies to behead buffalo.
There are many well documented stories of khukuries used as weapons of war. The knives are still issued to Ghurkas today; and they have reportedly decapitated enemies with them, and have even been known to stike a powerful enough blow to split a man from head to navel. The stories were enough to drive Argentinian troops to surrender during the Falklands War.
But, it is as a utility knife that the khukuri excells. It is capable of taking a fine shaving edge and has enough weight of force to chop better than any camp hatchet.
Himalayan Imports currently produces the best khukuries available. Each is hand forged from high carbon spring steel in Nepal by experienced traditional craftsmen. They are zone tempered, carry an unbeatable warranty, and are usually available at remarkably reasonable prices.
I hope you stop by the HI forum to meet some of the fine folks at our "cantina".
