Inigo Carmine said:The throwing axe is a light weapon compared to the javalin/club. (Also, javalins take a penalty when used in melee).
If all you're going to do is throw it, the throwing axe isn't that great; But if used in melee, it can be finessed, or used offhand for lower TWF penalties. I think it makes a great offhand weapon for a TWF dwarf who, after downing his current opponent, throws it into the back of an enemy 15 ft away.
Alternatively, it works well if both your weapons are throwing axes, and you can spend feats on them that improve both your melee and ranged attacks (weapon focus, specilization, etc).
Throwing Weapons are doubled range. So a throwing axe is 20 ft not 15.
