I am new, and I had an outside order for the knife block back in October. The customer later asked (through the host) why he had empty slots in his knife block. I assumed it must be for the steak knives and maybe the carving set. Is that right? The info. says that there are 16 slots, leaving room for extra pieces, but it is not specific. This same customer will be ordering from my show Friday, and wants to know what to get in order to fill up his knife block. Should he get both the steak and carving sets?
