Why are the molds for the Air Soap Cutter™ and Manual Soap Cutter™ in big blocks?
Efficiency and economy of motion is the primary reason, also less waste. Of course there is no tough crust or ash to deal with and you get a much better quality and saponification. At some point in production and growth, one has to move to fewer steps in the pouring and cutting process. Block form is the logical solution.
