Claim:
A self-defense tool comprising: a generally S-shaped tool having at one end thereof a ring portion for finger placement; a handle portion for holding said S-shaped tool, said handle portion being located between said ring portion and a blade portion; and said blade portion having a tip portion at an opposite end of said S-shaped tool, wherein said handle portion further comprises a cavity therein wherein said blade portion is rotatably interconnected to a back end of said handle portion and configured to be rotated and stored in a closed position within said cavity thereby forming a foldable self-defense tool; and said self-defense tool further comprising means for auto-releasing said blade portion from said cavity wherein said auto-release means includes a trigger activation member that extends generally parallel to said ring portion so as to be activated with a pressing of a finger inserted within said ring portion, said trigger activation member extending from said ring portion internally into said cavity and having at its opposite end a chamfered portion that is engageable with a sheer pin member wherein when said trigger activation member is pressed, said trigger activation member is caused to slide under said sheer pin member, said sheer pin member being movable so as to be pushed downward by the engagement of said chamfered portion with said sheer pin member and wherein a spring leaf member that has a normal tensioned position when said self-defense tool is in a folded closed position, is released to apply a forward urging at a bottom inside curve of said blade portion, thereby moving the blade portion forward and out of said cavity where said blade portion is in a fully opened locked position by the engagement of said blade portion with a tang portion of said handle portion.
