A railroad coupler knuckler meets AAR contour requirements and it includes unique external weight reducing features that strategically reduce weight without compromising strength or fatigue life. The design of the railroad knuckle of the present invention allows for formation of the knuckle through forging or coreless casting techniques and thus allows for the use of a better grade of steel compared to AAR Grade E and such forged or cast knuckle will yield much higher fatigue life compared to cast knuckles.
