It's best to see what your evaluation criteria are. Generally speaking, there are many enterprises making water knives in China, especially in the south. The famous ones are Dida Water Knife, Xusheng Water Knife and Foshan Yongda. There are Hyde and Otov in the north. However, if it is purely from the cutting performance, it is better to let it flow, but its price is also higher than that of domestic water knives, and if there is no high requirement for cutting accuracy, there is no need to use such a good one. So it depends on what your evaluation criteria are. But no matter what kind of water jet is used, the abrasive is universal water jet sand garnet.
