Nice,my mind is pretty much set on the chiruwa ang khola,just wondering, is there a price difference between the villager model and the finished one?
It's hard to generalize about prices. The biggest difference, I think, is whether you are in a position to wait for a DOTD, since those prices can be much lower than the more common price for a given model. Especially for holiday DOTDs. But then you have to be quick to snag one before some other shark grabs it. Or you could email Yangdu, tell her what you'd like, and sometimes the price is quite reasonable.
A villager khukuri is not necessarily inferior in any way to a polished one. It's really easy to polish a blade and handle if you like that look. Some people, including me, prefer the satin finish. Also, if you plan to use your khukuri for chopping or camping, a polished blade won't stay polished for long. And a highly polished handle might be a little more slippery in damp conditions than a comfortably smooth handle.
I have an excellent CAK (17", 31 oz), but I've come to prefer the ASTK model (which usually comes with chiruwa style handle like the CAK). Both are villagers, both have small imperfections that don't matter to me, and it's hard to imagine any usage that would cause them to break. If you accidentally hit a rock or hard bone, you might get chipping. The tip is soft steel, so it could bend if it hits something hard, but that could be hammered straight. Of course anything can be broken if you try hard enough. Even Sauron's Ring of Power was finally destroyed in the fires of Mount Doom.
Your comment about being able to break "vices and chisels, hammers and plyers" reminds me of why I don't lend out tools anymore.
I think the 2-for-1 warranty on the CAK was discontinued because some people were abusing it.
