… or “cheese harp”. It’s used to cut the coagulated curds into equally sized pieces during the cheese making process. I made one since I either didn’t like the ones you can buy at the store or they are suited for large 50 l batches of milk. I needed one for my small 4-5 l milk portions that fits my pot.
It’s made from two aluminium profiles, a little scrap wood as a handle and some stainless steel wire. It’s not a difficult build, though threading the wire was a bit of a game of patience. If you want to make your own: Measurements are below. Feel free to inquire if you have questions.
