Surprised no one else made it already so I made a simple replica.
The trophy looks 3D printed already in the show with its vertical layers and translucent tip. The handle is thinner in this design as I incorporated more traditional knife ratios.
It's printed as halves for easier printing so you will need to mirror the print. Have a single file with the whole knife and another two as two parts to print in a larger size that is accurate to the show based on your printer's print size.
Printed using Protopasta Gold Dust filament at 0.2 layer height, 15% infill, no supports/plate adhesion, using a Prusa MK3S+ at 140% file size.
