     BACKGROUND OF THE INVENTION 
     Various types of arrows are known in the prior art. Most comprise a cylindrical shaft connected to an arrowhead for striking a target or prey. However, such arrows can inadvertently staunch the very wound they are meant to inflict, slowing potential blood loss and increasing time to death. This increases suffering in the prey and, also, is makes collecting the prey more difficult as it may continue away from the archer over a prolonged time. 
     What is needed is a fluted arrow shaft and detachable arrowhead that includes an arrow shaft having a plurality of recessed grooves disposed evenly spaced apart longitudinally thereupon, between a fletching disposed at a distal end of the shaft, and an inset disposed proximal an arrowhead, said inset disposed underlying a rearmost extension of each of a plurality of blades comprising said arrowhead, wherein each inset is disposed for position in a wound inflicted by said arrowhead to effect increased blood loss drained along each of the plurality of recessed grooves, whereby debility and fatility of prey is more expediently effected. 
     FIELD OF THE INVENTION 
     The present invention relates to a fluted arrow shaft and detachable arrowhead, and more particularly, to a fluted arrow shaft and detachable arrowhead that includes an arrow shaft having a plurality of recessed grooves disposed evenly spaced apart longitudinally thereupon, between a fletching disposed at a distal end of the shaft, and an inset disposed proximal an arrowhead, said inset disposed underlying a rearmost extension of each of a plurality of blades comprising said arrowhead, wherein each inset is disposed for position in a wound inflicted by said arrowhead to effect increased blood loss drained along each of the plurality of recessed grooves, whereby debility and fatility of prey is more expediently effected. 
     SUMMARY OF THE INVENTION 
     The general purpose of the fluted arrow shaft and detachable arrowhead, described subsequently in greater detail, is to provide a fluted arrow shaft and detachable arrowhead which has many novel features that result in a fluted arrow shaft and detachable arrowhead which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof. 
     The present fluted arrow shaft and detachable arrowhead has been devised to expedite fatality from a wound inflicted by an arrow. Arrows presently seen in the art comprise a cylindrical shaft disposed endwise from an arrowhead. The shaft is usable to accelerate the arrow as a projectile and for controlling directable flight of said projectile. However, once pierced by an arrowhead, a wound can become inadvertently staunched by the cylindrical shaft whereby rate of blood loss is lessened and fatality of the wound thereby delayed. Prey can thus continue on, making collection of said prey more difficult and time consuming, and the prey&#39;s suffering prolonged. 
     What is needed is a fluted arrow shaft and detachable arrowhead whereby blood loss is facilitated along each of a plurality of recessed grooves disposed longitudinally along an arrow shaft to effect increased drainage of blood from a wound inflicted by an arrow, whereby debilitation of prey is expedited and kill and capture thereby more effectively enabled. 
     The present fluted arrow shaft and detachable arrowhead, therefore, includes an arrow shaft disposed between a proximal end and a distal end. A plurality of recessed grooves is disposed evenly spaced apart longitudinally along said arrow shaft, between said proximal end and said distal end. 
     An arrowhead is attachable at the proximal end, said arrowhead threadably engageable with a threaded collar portion disposed in the proximal end. Each of the plurality of recessed grooves is disposed to initiate at an inset disposed proximal the proximal end. Each inset is disposed proximal the proximal end underlying a furthermost extension of each of a plurality of blades comprising said arrowhead, whereby each of said plurality of blades positions each inset disposed on the arrow shaft interior to a wound inflicted by said fluted arrow shaft and detachable arrowhead to facilitate blood loss drained therethrough. 
     Each of the plurality of recessed grooves is deepest at each associated inset, whereby blood flow into the inset, and thence along each of the plurality of recessed grooves, is effected when the arrowhead pierces targeted prey. Each of the plurality of recessed grooves may be disposed along a gradient, deepening toward the inset, from a shallowest portion disposed at the shaft distal end, to a deepest portion, disposed at the inset. 
     An elongate threaded member is disposed upon the arrowhead for securement into the threaded collar at the shaft proximal end. Importantly, this threaded member is disposed to project into the shaft when screwed therein and underlie each inset projected into the shaft in parallel with a portion of each of the plurality of recessed grooves, whereby a relative decrease in diameter of the shaft effected at each inset does not decrease tensile strength of the arrow, said elongate threaded member disposed inserted into the arrow therein. 
     Once the arrowhead pierces a prey, blood therefore is drainable along each of the plurality of recessed grooves to facilitate blood loss from the quarry and thus expedite debility of the prey, and fatality resultant from the wound, whereby kill and capture of the prey is more expediently effective. 
     Thus has been broadly outlined the more important features of the present fluted arrow shaft and detachable arrowhead so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. 
     Objects of the present fluted arrow shaft and detachable arrowhead, along with various novel features that characterize the invention are particularly pointed out in the claims forming a part of this disclosure. For better understanding of the fluted arrow shaft and detachable arrowhead, its operating advantages and specific objects attained by its uses, refer to the accompanying drawings and description.

     DETAILED DESCRIPTION OF THE DRAWINGS 
     With reference now to the drawings, and in particular  FIGS. 1 through 4  thereof, example of the instant fluted arrow shaft and detachable arrowhead employing the principles and concepts of the present fluted arrow shaft and detachable arrowhead and generally designated by the reference number  10  will be described. 
     Referring to  FIGS. 1 through 4  a preferred embodiment of the fluted arrow shaft and detachable arrowhead  10  is illustrated. 
     Use of arrows to fell prey is well known in the art. Most arrows seen in the art comprise a cylindrical shaft connected endwise with an arrowhead. The arrowhead pierces prey, to inflict a targeted and potentially fatal wound. However, the shaft itself may staunch the wound, impeding flow of blood therefrom, whereby fatality resulting from the arrow&#39;s impact can be delayed. 
     The present fluted arrow shaft and detachable arrowhead  10  has been devised to prevent inadvertent staunching of a wound inflicted by an arrow and facilitate free flow of blood from such a wound, whereby blood is drained from prey more rapidly, and kill and capture of said prey is expedited. 
     The present fluted arrow shaft and detachable arrowhead  10 , therefore, includes an arrow shaft  20  having a plurality of recessed grooves  22  disposed longitudinally thereon, each of said plurality of recessed grooves  22  disposed evenly spaced apart between a proximal end  24  of the shaft  20 , connected with an arrowhead  70 , and a distal end  26  of the shaft  20 , wherein a nook  72  is adorned with a plurality of vanes  74  comprising a fletching  76 . 
     Each of the plurality of recessed grooves  22  enables passage of blood from a wound inflicted by the arrowhead  70 , wherein flow of blood along each of the plurality of recessed grooves  22  facilitates bleeding and thus debilitation of the prey whereby capture and kill is expedited. 
     The arrowhead  70  is attachable at the proximal end  24 , there fittable into a threaded collar portion  28  disposed endwise in the shaft  20  proximal end  24 . Each of the plurality of recessed grooves  22  is initiated at an inset  30  proximal the threaded collar  28 , a minimum distance from the proximal end  24  of the shaft  20  whereat each of a plurality of blades  78  of the arrowhead  70  extends over the inset  30  of each of the plurality of recessed grooves  22 , whereby cleavage of flesh effective by each of said plurality of blades  78  engenders flow of blood from the wound into each inset  30  for drainage along each of the plurality of recessed grooves  22  and thus out of the prey. 
     Each of the plurality of recessed grooves  22  has a maximum depth at each associated inset  30 . Tensile strength of the shaft  20  is not weakened, however, by this reduction in diameter of the shaft  20  at each inset  30 , as an elongate threaded member  80  of the arrowhead  70 , connectable and securable into the threaded collar  28 , projects into the arrow shaft  20  and projects underlying each inset  30  into the arrow shaft  20 , to thereby secure the arrowhead  70  to the shaft  20  and maintain integrity of the shaft  20  throughout the proximal end  24 . 
     Each of the plurality of recessed grooves  22  may be disposed along a gradient from a shallowest depth most proximal the arrow shaft  20  distal end  26 , and a deepest depth at the inset  30 . 
     The fluted arrow shaft and detachable arrowhead  10 , therefore, is enabled to effect increased bleeding from a wound inflicted by an arrow, whereby blood loss from said wound is facilitated and the respective prey is brought down more rapidly for expedited kill and capture, as desired.
