The dual spreading arrowhead of claim 2 further comprising:each of said shoulders having said third edge extending at least ninety degrees in rotation from said second edge, and each of said shoulders extending from said third edge in a square edge to said spine wherein said square edge attains an angle to the longitudinal axis of said dual spreading arrowhead; and said square edges of said shoulders in cooperation with said spacer retaining said blades in the flight position until said tips cut a target upon contact and said blades open to the deployed position. 4. The dual spreading arrowhead of claim 3 further comprising:said blades stacking back to back and said shoulders entering said slot, said tips positioning away from said head, and said tips orienting mutually outward. 7. The dual spreading arrowhead of claim 3 further comprising:said spacer having two sloped surfaces abutting said shoulders. 8. The dual spreading arrowhead of claim 7 further comprising:each of said sloped surfaces abutting one of said shoulders.
5. The dual spreading arrowhead of claim 2 further comprising:said head having a forward surface orienting towards said blades, a round cylindrical shape having a diameter, a round neck opposite said forward surface and centered upon said head having a diameter, and a round stem outwardly from said neck and centered upon said neck having a diameter; said neck having its diameter less than that of said head, said stem having its diameter less than that of said neck; said head having a length and said slot having a depth at least half of the length of said head; and said head having two coaxial apertures transverse to said slot and to said longitudinal axis of said head wherein said apertures receive said elongated cylinder. 6. The dual spreading arrowhead of claim 5 further comprising:said forward surface having a bevel. 9. The dual spreading arrowhead of claim 5 wherein said elongated cylinder is either a pin or a screw.10. The dual spreading arrowhead of claim 9 wherein said elongated cylinder is a screw.
11. A mechanical broadhead capable of mounting upon a shaft, comprising: a head having a longitudinal axis and a slot transverse to the longitudinal axis; a spacer placing into said slot; two blades having an elongated trapezoidal form, said blades operatively connecting by an elongated cylinder, said elongated cylinder inserting into said head rearward of said spacer; said blades rotating in said slot and said mechanical broadhead having a longitudinal axis; and wherein said mechanical broadhead transitions from a flight position with said blades angularly spaced near each other to a deployed position with said blades rotating outwardly from each other and attaining at least one hundred eight degrees of separation, as during a hunt. 12. The mechanical broadhead of claim 11 further comprising:said head having a forward surface orienting towards said blades, a round cylindrical shape having a diameter, a round neck opposite said forward surface and centered upon said head having its diameter, and a round stem outwardly from said neck and centered upon said neck having its diameter; said neck having its diameter less than that of said head, said stem having its diameter less than that of said neck; said head having a length and said slot having a depth at least half of the length of said head, said slot being opposite said neck; and said head having two coaxial apertures transverse to said slot and to said longitudinal axis of said head wherein said apertures receive said elongated cylinder. 13. The mechanical broadhead of claim 12 further comprising:said forward surface having a bevel.
14. The mechanical broadhead of claim 11 wherein said elongated cylinder is either a pin or a screw.15. The mechanical broadhead of claim 14 wherein said elongated cylinder is a screw.
16. The mechanical broadhead of claim 11 further comprising:each of said blades having a tip, a first edge inward from said tip, a second edge inward from said first edge, a third edge rotating from said second edge, and a spine from said third edge to said tip; each of said blades having a front spanning said first edge, said second edge, said third edge, and said spine, and a back opposite said front and mutually parallel and spaced apart from said front; each of said blades having a foot opposite said tip, each of said feet having a rounded form of greater width than the distance from said spine to said said mechanical broadhead having a longitudinal axis; each of said feet having said third edge extending at least ninety degrees in rotation from said second edge, and each of said feet extending from said third edge in a square edge to said spine wherein said square edge attains an angle to the longitudinal axis of said mechanical broadhead; and said square edges of said feet in cooperation with said spacer retaining said blades in the flight position until said tips cut a target upon contact and said blades open to the deployed position. 17. The mechanical broadhead of claim 16 further comprising:said spacer having two sloped surfaces abutting said feet. 18. The mechanical broadhead of claim 17 further comprising:said blades stacking back to back and said feet entering said slot, said tips positioning away from said head, and said tips orienting mutually outward; said spacer having two sloped surfaces abutting said feet; and each of said sloped surfaces abutting said squared edge of one of said feet.
19. A mechanical broadhead capable of mounting upon a shaft, comprising: two blades having an elongated trapezoidal form; said blades operatively connecting by an elongated cylinder through a head, said head having a longitudinal axis and a slot transverse to the longitudinal axis, said blades rotating in said slot and said broadhead having a longitudinal axis; a spacer placing into said slot interiorly of said head and said blades; wherein said mechanical broadhead transitions from a flight position with said blades angularly spaced near each other to a deployed position with said blades rotating outwardly from each other and attaining at least one hundred eight degrees of separation, as during a hunt; each of said blades having a tip, a first edge inward from said tip, a second edge inward from said first edge, a third edge rotating from said second edge, and a spine from said third edge to said tip; each of said blades having a front spanning said first edge, said second edge, said third edge, and said spine, and a back opposite said front and mutually parallel and spaced apart from said front; each of said blades having a shoulder opposite said tip, said shoulder having a rounded form of greater width than the distance from said spine to said second edge, said shoulder including said third edge; said mechanical broadhead having a longitudinal axis; each of said shoulders having said third edge extending at least ninety degrees in rotation from said second edge, and each of said shoulders extending from said third edge in a square edge to said spine wherein said square edge attains an angle to the longitudinal axis of said mechanical broadhead; said blades stacking back to back, said shoulders entering said slot, said tips positioning away from said head, and said tips orienting mutually outward; and said square edges of said shoulders in cooperation with said spacer retaining said blades in the flight position until said tips cut a target upon contact and said blades open to the deployed position. 20.
