So I was wondering. Will a bullet be split in half if it hits a butter knife that is fixed in place? Have there been experiments to test that?
In the television show Penn and Teller Tell A Lie, a competitor to Mythbusters, they conduct an experiment to try this.
Here is a YouTube video of the result.
In the single instance they show with a slow motion camera, the bullet is indeed at split in half - or at least, fragmented into pieces - by a normal butter-knife. This is not a large sample, and doesn't demonstrate it works with all bullets or all butter knives, but shows that it is, in fact, possible.
Bonus: Another video on the stunt using a machete from a source I have no particular reason to trust.
Mythbusters conducted a similiar experiment. But they used an axe. The answer is yes. It is possible. At least with a particular type of axe and with the particular bullet and gun, and with the right distance. quoting Wikipedia:
