Spherical anti-slip fastener remover

A spherical anti-slip fastener remover bit comprising:

• a screw bit body;
• the screw bit body comprising a plurality of laterally-bracing sidewalls, a first base and a second base;
• each of the plurality of laterally-bracing sidewalls comprising a first lateral edge, a second lateral edge, a convex surface, a concave surface and an engagement cavity, the convex surface being positioned adjacent to the first base, the concave surface being positioned adjacent to the convex surface opposite to the first base, the convex surface and the concave surface being oriented along a rotation axis of the screw bit body, the first lateral edge and the second lateral edge being positioned opposite to each other across the convex surface and the concave surface, the engagement cavity normally traversing into the convex surface, the engagement cavity traversing into the screw bit body from the first base towards the second base, a cross-section of the engagement cavity being a triangular profile, the triangular profile extending from the first lateral edge towards the second lateral edge;
• the first lateral edge of an arbitrary laterally-bracing sidewall among the plurality of laterally-bracing sidewalls being a sharp edge formed in between the engagement cavity of the arbitrary laterally-bracing sidewall among the plurality of laterally-bracing sidewalls and the convex surface of an adjacent laterally-bracing sidewall among the plurality of laterally-bracing sidewalls, or the first lateral edge of the arbitrary laterally-bracing sidewall among the plurality of laterally-bracing sidewalls being a sharp edge formed in between the engagement cavity of the adjacent laterally-bracing sidewall among the plurality of laterally-bracing sidewalls and the convex surface of the arbitrary laterally-bracing sidewall among the plurality of laterally-bracing sidewalls;
• and
• the plurality of laterally-bracing sidewalls being radially positioned about the rotation axis of the screw bit body.
