Physics of knife throwing
"It is important to keep in mind that a knife throw happens instinctively, without thinking, much like walking or riding a bike. You must not try to think of the throw! Helpful notions like 'release when the knife is pointing exactly at the target' are necessary to learn the motion sequence, but your brain will automatically adjust to release the knife in the right moment (a little earlier). Another example for this is 'holding higher'. Here too, you just can`t explain what exactly you change in your throw."
