The broadhead of  claim 2 , further comprising a pair of secondary blades, each secondary blade of the pair positioned in a slot 180° apart from each other, wherein the blade device is positioned in a pair of slots located between the slots in which the secondary blades are positioned.  
   
   
       4 . The braodhead of  claim 1 , wherein the blade device has a pair of blades extending from the point at the first end, the pair of blades being in the same plane.  
   
   
       5 . The broadhead of  claim 4 , wherein at least a portion of the pair of blades are positioned in a pair of slots of the ferrule, the pair of slots being 180° apart from each other.  
   
   
       6 . The broadhead of  claim 1 , wherein the tip slides over the second end of the ferrule.  
   
   
       7 . A broadhead comprising: 
 a blade device having a pair of blades joined at a point, the pair of blades being in the same plane and each blade of the pair terminating in a threaded tab;    a ferrule having at least a pair of slots disposed 180° apart about the circumference of the ferrule, each slot engaging one blade of the pair of blades of the blade device;    a transverse slot disposed at an end of the ferrule aligned with the pair of slots of the ferrule, the transverse slot accommodating an interior portion of the point of the blade device; and    a retaining ring having a threaded interior for engaging the threaded tabs of the blade device to secure the blade device to the ferrule.    
   
   
       8 . The broadhead of  claim 7 , further comprising a tip member which is attachable to the end of the ferrule, the transverse slot being positioned at an end of the tip member.  
   
   
       9 . A broadhead comprising: 
 a ferrule having lengthwise slots;    a tip member having a transverse slot positioned on a first end of the ferrule; and    a blade device terminating in back end retaining tabs, the blade device being positioned in the transverse slot of the tip member at one end and in the lengthwise slots of the ferrule at a second end;    wherein a combined length of the ferrule and tip member is at least 80% of the combined length of the ferrule, tip member and blade device.    
   
   
       10 . An archery broadhead comprising: 
 a ferrule having blade-receiving slots disposed thereon;    a tip with a slotted front end and an open interior back end;    a retaining ring with threads disposed on its inner surface; and    a blade device having a pair of blades extending from a point, the pair of blades being in the same plane and terminating in threaded back end retaining tabs;    wherein,    an inside portion of the blade device fits into the slotted front end of the tip;    the open interior back end of the tip fits over the ferrule;    the threaded back end retaining tabs of the blade device fit into the blade-receiving slots of the ferrule; and,    the retaining ring screws onto the threaded back end retaining tabs of the blade device to secure the blade device to the ferrule.
