so i want to 3d print a karambit from counter strike because im just that thug. But im wondering, should and if yes then how I make it very sharp to order, or should i sharpen it after i order and how would i do that properly
3d printing does not produce knife sharp edges, and the properties of the available materials are inferior to cuttlery steel as well. Use one of the plastics materials with metal effect paint if you want a cosplay prop or martial-looking letter opener, or buy a conventionally forged one if you really want to hurt yourself and/or others. (Note that while they are a traditional Indo-Malayan tool, they are classified as illegal weapons in some jurisdictions)
