3D printed in hardened 6/4 Ti, this lockring tool weighs only 45 grams.  The handle is printed with spiral rifle reinforcements inspired by Columbus SLX tubing, and the tool head has 2 spline patterns to accommodate both Shimano/SRAM and Campagnolo lockrings.  While not as hard as tool steel, hardened 6/4 is harder and stronger than the steels used in many traditional cycling tools, and is 4-6 times harder and stronger than the aluminum used in high end lockrings.  Just as with it's matching chain whip, this tool is designed to be used on well maintained bikes and is NOT compatible with cheater bars
