You can try this in home!
I bet you think how to do photo like this.
i was coming back from work and this image came to may head.
I said to myself i need to do it.
Soon i reach home i knew how to do it.
I hang kitchen knife on the very tin fishing wire, i put my camera nikon d7000 with 50mm on tripod. i place myself in to position like i am throwing that knife. Camera was set to f/1.4 and focus just on the tip of the knife, So wire will be not visible and background will be blurry. Light came from the window behind me. I set self timer to triger the camera. And thats how this shot was made.
No need special equipment, just little bit of imagination.
