Ax1 + vaxis_rotate(Pt - Ax1, Ax2 - Ax1, Amt)

I prefer a point and direction, because it more clearly specifies the 
direction of the axis. With two points, the direction depends on the 
order of the end point vectors, which is workable but possibly more 
confusing. Also, I was making it similar as possible to the 
vaxis_rotate() function.
