The lever shears model can be considered to be a project enabling interdisciplinary, action-oriented teaching. As well as the primary technical drawing focus of teaching, other topics that can be covered include machine elements, assembly processes, and manufacturing technology. The lever shears model forms part of the extensive course providing an introduction to technical drawing. Comprehensive and well-structured instructional material supports wide-ranging use of the model in technical training. The approach involves teaching the systematic and transferable learning matter based on an operational mechanism.

The kit contains all the parts required to assemble a functional lever shears. The graphic symbolises standard and production parts, and represents fixed and moving connections differently. All parts are precision-manufactured on CNC machines and feature standard engineering tolerances and surface finishes. The parts are clearly laid out on a base plate. They are grouped into individual assembly sequences. The base plate is covered with a transparent cover panel on which a graphical representation of the assembly structure is printed. Multiple trays are stackable, providing for space-saving storage. The surfaces of the finished parts have a gunmetal finish to prevent corrosion.
