Many ways. It's not a double weapon, it deals 1d8, not 1d6, and crits x3.

http://www.d20pfsrd.com/equipment---final/weapons#TOC-Creating-New-Weapons Scroll down to sample weapons, it's called "khakkhara". I realize this post is like three years old, but for anyone else searching, here it is.

I'm surprised nobody has mentioned this combo with a Vorpal weapon. Just buy a vorpal weapon, summon the Cyclops, hand it the weapon and boom, 1 shot auto kill, no roll. Epic CR dragon? Still has a head, no problem. Per Vorpal, you don't even have to confirm, just get a 20 (and the wording on Flash of Insight specifies you choose the result of the die, aka, a 20).
