Maka Albarn's Schythe (Soul Edwards) and cuff link buttons.

thingiverse

My daughter was determined to be Maka Albarn from Soul-Eater on Halloween. So I designed a Schythe top and cufflink buttons specifically for her costume. Using the provided image as a design guide, along with pictures of the PPP figure to gauge proper scale for her size, helped me create an accurate design. The blade opening was too wide for our custom blade, so I created shims to keep it securely in place. The openscad file includes adjustable settings to fit your specific needs: you can re-size to suit your size, adjust the blade opening and shims as needed, and even modify the shaft opening to accommodate your preferred shaft. This setup also allows for creating jacket buttons.
