Does it make sense that the goedendag weighs only .2 more than this 1h counterpart(I'm using this word here loosely)? That it has only 25b in 2h mode, while the military hammer has 28b in 1h?
Both can be used in 1h and 2h mode, so why such a significant damage difference? Because the Goedendag has a thrust? Woop-de-doo. You shouldn't really bother with the thrust for any situations that don't require the use of the weapon's full range. No knockdown on the thrust means you're not maximizing the weapon's strengths by utilizing that attack direction for anything other than what was previously mentioned. 1 speed for 3 blunt damage is a pretty shitty trade off, especially when you're talking about blunt or pierce damage. 37 range is fairly huge, but you can't forget that the Military Hammer's stats are for when it's used with a shield. One-Handed weapons have to be balanced with the shield in mind.

I should probably throw out my disclaimer now, before anyone gets carried away. I realize what you're thinking when you compare this weapon to the goedendag, but one thing you should keep in mind, is that no one can be found using the Iron Staff past level 20, for anything other than a gimmick, "fun" round. Sadly, both of these weapons suck for anything other than saving money in strategus. They're poor weapons in crpg and should be slightly buffed to give people reason to use them, especially the goedendag; as it would better fill, or maybe even create, it's own niche spot among two-handed weapons.
My suggestion is simply to add 1 speed and 2 damage to the Goedendag. Or, if you want to emphasize the knockdown, add .3~ weight and one of the previously stated buffs.
There are a few other comparisons that I have, but due to not wanting this post to drag on too long, I'm saving them for later.
