I made something along that line, but on a much larger scale. It was for a round vat that was 48" diameter and about 24" deep. It was built for a Norbertine convent in California. Rather than try to cut the whole vat into cubes at once, the half round knife is pressed down through the curd to the bottom of the vat, turned 90 degrees and then lifted to cut the rest of the vat. Then the horizontal knife is used to finish the cut. They have been using the knives for several years and have been very happy with process so far. It reduced their curd cutting from around 15 - 20 minutes down to about 5 minutes.
