A deflection-resistant arrowhead includes a support body with a fixed spear-point blade attached to the tip thereof, and a plurality of pivotally attached, mechanically expandable blades. The expandable blades include integrally formed spurs at end portions thereof, which are provided to extend outwardly from the front of the support body, adjacent the base of the fixed blade, when the expandable blades are closed. The support body has slots formed in the sides thereof, to receive the pivotally attached expandable blades. The support body is also slotted at the front central portion thereof to receive the base portion of the fixed blade. The expandable blades normally remain in a closed configuration thereof, by means of an elastic retaining ring located behind the spurs. Upon contact with a target, the outstanding spurs force the expandable blades to open, simultaneously moving the retaining ring rearwardly on the support body.
