sword that teleports to location of where it was thrown. and used like waystone

so im trying to make a sword or more accurately a sai, that can be used like a sword but can also be thrown and when thrown will teleport the thrower to where it lands. i also want to make it have a hotkey lets say "c" that when pressed when holding the sword will take you to your bed/spawn point if you are standing sitll for 5 seconds. bonus if you can make it so you can make waypoints (max three) and teleport to each of them instead of the bed thing but i thought that may be more simpler.
