This gage has a knife-edge base and a needle point contact which has
been hardened and ground . The knife-edge base has a cutout so that
the conical point can be precisely positioned for close work . Point is
1/2″ (12 .7mm) long with a 60º included angle .
In action, the inspector gently pushes the point down to read zero with
the base and then pushes down to make the needle point contact the
workpiece to take the measurement .
