Warning:
This model is not intended for load-bearing or structural support. If excessive external force is applied to the blade, there is a high risk that the blade will penetrate the plastic material. This risk is particularly pronounced when using a two-piece design. If you plan to use it to cut objects that require significant force to cut through, please be sure to switch to a professional blade holder. However, if you are just using it to handle smaller objects with a softer texture that are easy to cut, you can use it with complete confidence.

Proportion: 1:1

Update note: If you encounter any problems when using the all-in-one design, you can print it in the following way:

07 Ultra-Thin Blade Rev 3 Front End — Print 1 piece
07 Ultra-Thin Blade Rev 3 Back End — Print 1 copy
07 Ultra-Thin Blade Rev 3 Pins — Print 2 pieces

I originally reminded everyone that the strength of metal is much greater than that of plastic, which is common sense.

Scaling ratio: 1:1

Background: I really like the Rexford Knives RUT

1) Fix and lock the blade in a safe and reliable way;
2) It is compact in size and easy to carry around;
3) Reserve a hole for stringing, making it convenient to string a section of parachute cord;
4) It is easy to operate and offers a smooth user experience.

During this process, I conducted three iterative optimizations successively:

First Edition: The blade is too thin, making it inconvenient to take out and put back the blade;
2nd Edition: The thickness of the blade is moderate, but the blade is still difficult to remove, and the reliability of the locking mechanism needs to be improved;
Third Edition: The thickness of the blade is just right, and the blade is firmly locked. At the same time, the window opening is enlarged, making it more convenient to retrieve the blade.
