Sakai Takayuki Aonikou Blue-2 Carbon Steel

If you're looking for a real carbon steel knife but would also prefer a standard European style handle, these are a great choice. They're quite popular as they offer great performance but the blades are not overly fragile since they're made more in the Western style and the edges aren't paper thin. A great choice if you're carbon-curious and don't want to break the bank (or break the knife too easily). Of course they're still going to be more brittle than most stainless knives, and you MUST keep them dry and clean and properly stored to keep rust at bay.
