This CAD template is designed for building a safe kids’ knife.It combines the blade and handle in one precise model and allows easy embedding of M5 thread inserts. This enables accurate pre-drilling with a 4 mm drill and secure fastening of the template when needed.

All edges are chamfered for easy marking and transferring the contours onto wood or other materials.The design is based on a real, built, and tested knife.

Bonus: In addition to the 3D files, the blade is also provided as a DXF file – perfect for laser cutting or water jet cutting from steel

Included Files:

• STL – ready for 3D printing the template
• STEP – for further CAD modifications
• DXF – 2D blade contour for laser or water jet cutting
