A latching mechanism used in conjunction with a butterfly knife may be cumbersome to latch and/or unlatch, and the latch may become loose and not properly hold the knife in either the open or closed position (i.e. the latch may not be reliable). An improperly latched butterfly knife may be hazardous, dangerous, and cause potential injury to the user or others. Some of the prior art latches for butterfly knives require the use of moving part or parts making it more complex for the user to use. Such moving parts may be subjected to wear and tear leading to possible failure of the latch. Also, it is desired that these knives be easily and quickly opened or closed by the user, especially in instances such as emergency and/or combat situations. It is a continued need and desire to provide latches for butterfly knives or latching butterfly knives that are more simplistic, easier, and safer to use. Furthermore, devices or components for helping the user move a butterfly knife between the open latched and closed latched positions are continuously needed and desired as well.




Therefore, the present invention discloses and provides a magnetic latch for a butterfly knife and a magnetically latching butterfly knife, and the present invention overcomes the problems, disadvantages, and limitations of the prior art.
