I bake relatively crusty challah about once or twice a week for home. Leave it sitting out, and I usually end up having to slice a thin bit off the exposed end because it's just wayyy too crusty to eat. I make the biggest mess with a serrated edge. Purchased a cheap $12 nakiri, it cut like butter through the whole loaf (besides the initial uber dry exposed slice). Gonna take it to work (brunch spot, toasts, prep and salads) see how well it fares to a full day of cutting toasts and veggies. If I mess it up, whatever. I'll just buy a new one.
