1. A ball valve assembly, comprising:
a ball having a fluid pathway and a leading edge portion, wherein the ball is configured to rotate between an open position and a closed position, the fluid pathway is configured to align with a fluid passage of the ball valve assembly while the ball is in the open position to enable fluid flow through the ball valve assembly, and the fluid pathway is configured to be offset from the fluid passage while the ball is in the closed position to block fluid flow through the ball valve assembly;
wherein the leading edge portion comprises a first leading edge configured to cut a line extending through the fluid pathway as the ball rotates from the open position to the closed position, the leading edge portion comprises a second leading edge configured to engage a seal of the ball valve assembly as the ball rotates from the open position to the closed position, and the first leading edge is positioned radially inward from the second leading edge;
wherein the ball comprises a body and an insert coupled to the body by a fastener, and the first leading edge is formed on the insert;
wherein the body has a first portion of a shoulder, the insert has a second portion of the shoulder, and a head of the fastener is configured to contact the first portion of the shoulder and the second portion of the shoulder while the fastener is engaged with the insert and the body.
