I don't mind an off-center blade. Hell, even blade play doesn't really bother me anymore. But when I get a knife (especially a fixed blade), it just really bugs me when the plunge lines are off. Anyone else?
I mean, its a fixed blade. It is much easier to make than a folder. Not a lot can go wrong (the plunge lines being something that can), but it seems like I always end up with uneven plunge lines.
