I'm sorry to awake you from your dream, but thats just a 1h
Otherwise it would say "Axe, Great Weapon" not just "Axe".
All the RR Big Choppas are classified as 1h for some reason.
For those that don't know "Big Choppa" = 2h
If you're a dwarf and looking for something not as good but still nice, try the Blessed Labrys from dwarf chapter 11. Stats of a 2H, one handed.
