The article presents the results of two interrelated studies. The first one is related to assessing the possibility of using a water-polymer ultra-jet as a diagnostic tool for cutting devices that are used for plastic recycling. The second one is related to the development of a new tool design. As a result of the research, it is shown that both the method of water-polymer diagnostics and the proposed design of the knife have prospects to practical application. Rapid wear of the tools for recycling polymer materials is the primary problem that is advisable to eliminate in first order because the idle equipment leads to financial losses. Therefore it is necessary to develop tools with high values of wear resistance and which at the same time have a low cost. A model of a prefabricated tool for recycling composites is proposed, which potentially has high performance properties. The main feature of new tool is its geometric configuration that allows to increase the tool resource and significantly saves the material for its manufacturing. The increase of resource occurs due to the following: if the cutting plate of the tool is worn, it can be removed off the tool, flip it 180 degrees and reinstall. Economy of the material is also due to a decrease in size of the plate, which is fixed to the tool body with countersunk screws head. The research results are confirmed by comparative analysis of various diagnostic methods and strength analysis of the tool.
