This full size, 60mm cross is heavy duty, minus the heavy. That is because of the solid layer of machined, aerospace-grade carbon fiber that makes up the center-mass. Looking at the cross, the entire black detail is a block of carbon fiber. From the front one might notice subtle hints of what it is... But, from the side it looks like exotic wood. The grains of the carbon fiber weave in and out like grains of ebony shimmering in the light. It is by far one of the most exciting pieces we have made and it gave birth to the rest of the machined carbon pieces we have in our line. Heavy duty... Minus the heavy... Plus a lot of amazing.
