Jon and Korin have posted that carbon knives will inevitably become not 100% straight over time, and makers check for straightness by sight, not necessarily as nitpicky as we are. I'm assuming that's the case with this knife but wanted to ask. Otherwise I'm really impressed with it. Handle is great, despite many bad things I've read and the spine is eased. Choil a little rough, but not as bad as I was expected.
