Double bitted war axes were used in combat.
Friend of mine has a double bitted axe head estimated 800 years old and were also used in later medieval times.
Posting pictures of single bitted axes is like posting pictures of 1h swords and saying there were no 2h. They were alot less common but not non existent.
However not the size of the blades on this axe, need the axe head reduced somewhat or weight would not be feasible for hitting anything other than splitting logs.
Oh and call it Snaga.
