Even in puritan cultures that intentionally eat plain food to shun "hedonism", food becomes a vehicle for virtue signaling. The suffering is a ritual practice. Food, even then, plays a critical cultural role.
Yeah, but one can view that cultural tradition and conclude that their culture does not value the deliciousness of food as much as some other cultures.
Some dedicated bread lames are curved (see OP's frontmost lame) which can make certain swooping curved cuts easier. I generally lack the skill to be able to do it consistently, though, so a flat razor blade holder generally works best for me.
