This is model of highly detailed tech chainaxe | chain axe for Astra Militarum and Adeptus Astartes. I used gemstones as energy source. Also I added radiator and tubes for cooling. Sensor to monitor and control the operation of the chain mechanism. And buttons to engage the chain mechanism.

The chainaxe is the preferred close combat melee weapon of many of the military forces of the Imperium of Man and versions are also used by the warriors of the Heretic Astartes, Traitoris Militarum, the Orks and the Asuryani.
