CubeLW:
As far as the warranty goes, it probably General Use, as Karda says.
As far as what you actually use it for, that probably depends on the spine thickness as much as anything. I looked back at the most recent posting of a Baby CAK, but all it gave was the overall length, not the weight or spine thickness.
I'd say if the spine thickness of yours is 1/4" or more, you can probably use it for anything that makes sense in relation to its size: probably anything except chopping thick pieces of wood. With a knife that small, you'd probably wear out your hand trying to do any serious chopping.
For the larger HI khukuris that are warranteed for heavy chopping, the weight is usually up around 2 oz per inch of overall length, sometimes a little less. If you have the means to weigh yours, what is the overall length, weight and spine thickness?
