A butter knife and butter.

     We use this type of simple machine all the time!  It is great for splitting, slicing, cutting, and piercing.  When I push down on this machine, it changes the direction of the force to out!

     The tradeoff with this simple machine is that there is a short distance to travel, but you must use a lot of force!

     Which simple machine is it?
