The safety catch model forms part of the extensive GUNT course providing an introduction to technical drawing. The didactic approach involves teaching the systematic and transferable learning matter based on an operational mechanism.
All parts, made from steel, are precision-manufactured on CNC machines. The surfaces of the steel parts have a gunmetal finish to prevent corrosion.
Comprehensive and well-structured instructional material supports wide-ranging use of the model in technical training.
Optimal learning is established when one model is used with two/three students.

- Reading and understanding technical drawings and parts lists
- Production-oriented and standardised representation of parts:
  dimensioning, surface finish and tolerance specifications
- Technological aspects: including; material selection, functions,
  manufacturing methods, and work planning.
