"Piranha" utility folding knife
Description
This is my remix of the folding knife design which i like, but wanted to improve. The ring position is changed to the bottom for the better and more convenient grip. Finger guard added to prevent the finger slip into blade. Locking in closed/open position done by spring, three spring hardness can be choose, i would recommend to start with 1.5 mm. One handed opening/closing, may be opened by twist around a finger, make satisfying clap sound, can be used as fidget (be careful doing that since the blade is very sharp especially when new, and remember this is not a toy). I would suggest to add grease/oil into the holes while assembling, to assure smooth functioning. No supports needed while printing. Remove sacrificial layer into holes by 3 mm drill bit after printing. Any questions/suggestions, fell free to leave a comment.
