How to Model a One Piece Knife in SolidWorks?I recently saw a beautiful knife that was crafted out of one piece of twisting metal.It turned out to be the “One Piece Knife” designed by Johanna Gauder. This knife is madeout of a stainless steel sheet and its flowing form isn’t interrupted by an added handle.In today’s tutorial you will discover how to model this knife in SolidWorks yourself.Enjoy!Disclaimer: The intellectual property depicted in this 3D model, is not affiliated with or endorsed byJohanna Gauder.
