It is so heavy duty, you will have an impossible time breaking it without a vice and steel sledge hammer!
by hand, you will have an impossible time breaking a .187 skinny ash 1 (if you don't believe me watch knifetests.com destruction tests of the skinny ash, and FFBM!)
the KZII will be so much stronger than even a .50 HI khukri!
The lateral strength is amazing.
Remember, the traditional Khukris are spring steel. (5160 typically), which while a decently strong steel, is not in the same class for later strength and impact resistance as infi. The weak point of many HI khukri's is the stick tang handle. If you go with a full tang it will be stronger. The handle slabs, which are simple wood, will be more apt to break as well.
Where you will really win is with edge retention, resistance to corrosion, impact resistance, lateral strength, resistance to chipping............pure awesomeness, and just about every other area you can think of.
Price is about the only down side, but when you consider that with most infi, you will maintain your value at the least, you get what you pay for.
If you ever do manage to accidentally break it (ie Hulk Get Mad!), Busse will replace it.
