But like Bill said nuts and chocolate are butter compared to steel.
Different Burke!
But seriously, pumbaa, what kind of nuts are you cutting? How frozen is the stuff you are cutting? You are certainly not alone in this fear! Not to stop you from furthering your addiction (*ahem*
education) by buying sweet new toys, but I haven't slept all night and have work in half an hour, so I've got nothing else to do, and I want to address these concerns right quick. Imma let you finish.
I have cut up blocks of chocolate with everything from a CCK1303 to a Rader custom. All of them do fine.
Nuts? I've yet to come across a nut that is as hard as chocolate, and chocolate, as I've said, does fine. I don't chop walnut shells with it or anything, but that's because it'd be messy, not that it would hurt the knife(plus I don't eat them, lol).
Frozen goods...well, if it's still a frozen solid block, it is far more likely that in the process of cutting it, a weak line in the ice will crack and split whichever way it goes. So it doesn't matter what you are using, if I try to pry a crate of chicken breasts apart straight from the freezer, they will split through the middle as easily as they will apart, because it's more like cracking a brick. If it's thawed at all, to the point where the ice is flaky, you can, again, cut it with pretty much any knife.
The reason that people's cheapo beaters get so much unannounced attachment from their owners is because they are ok with abusing them. This is why owners of Cold Steel knives swear by them--they see the guys who make them abusing them like teenagers and trust that they will do the same for them, and in the course of their non-thriller-movie life, it handles cutting up packages, food, roots, and rope just fine.
I remember the first time I was cutting a fish with my Tojiro dp gyuto(my first good knife) and was pissed at my boss and working kinda fast--I wasn't thinking about my knife, only the fish, and ended up bending the blade a LOT--it was flexed like a fillet knife, and if you'd asked me a month before, I would never have done that for fear it would break. But after that, I liked using it even more, because I trusted it's strength. IMO, the thing that creates the "feels like an extension of your body" feeling is not balance, comfort, or size; it is the trust that the thing won't break and you can trust it's limits---yes, it'll chip the edge if you use it to scrape the grill grate, and it is possible to hammer it into a frozen block and twist, and crack something in the process. But if you are just cutting food and not treating it like a prybar, hammer, or sword, you will be fine.
