GENEX is a new style of  X handle hex wrench from Runwell Japan.

Designed to prioritize a firm grip and torque transmission, the GENEX8 is an X-shaped 8mm hex wrench used to tighten and loosen the hex socket bolts that secure crank arms. 

Its functionality includes quick turning, pre-tightening, and final tightening, and the opposite side of the bit features a 6mm hex wrench.

The surface is plated with hard chrome, which is said to be the hardest electroplating material and has excellent abrasion resistance, resulting in a premium finish.
