Hi guys- I am a new consultant and did a search for the answers I am looking for but didnt find the answer. Does the Pizza cover fit the old pizza cutters that didnt have a cover? I have a customer that wants the cover but doesnt know if it will fit her cutter. She also has problems with the cheese knife- I dont have this item so I dont know how to help her. She just cant get it to work properly so she is not using it. Anyone have any suggestions? Any help would be appreciated- You guys are great!!! Thanks.
