The STEX is a high polish steel handled wrench with all the key hex head bits stuck into it. It has a 3 and 4mm bit in one end and a 5 and 6mm bit in the other. Both bits are easily replaceable via the 2.5mm grub screws in the end. The STEX is 100mm long, making it not quite as compact as is cousin the SUSX, but maybe a bit better as a work bench multi tool.
