What Steve said. I love the sirupatis--they're quite tough, though fairly thin and light. I've never held a chitlangi, so can't speak about them. Kobras are the only HI khukuri that I know of that doesn't have a "break it by prying and we'll replace it" warranty; they are much thinner than the others. I had a chainpuri bend more than I thought would be practical for a user, and, though I was able to bend it back, I arranged a trade; HI took it back in exchange for a more-robust knife that fits my hard-wood-chopping needs better. You might also consider a Gelbu special, as those are a little lighter than most, but still do good chopping. Have fun!
