My only problem with the Spathovaklion is it's so much harder to see than the other blunt 1h's. Fix that and I'd be a happy puppy.
Rusty, you should use Final Boss' texture pack, it makes it bright silver and easy to see. Also makes your Military Hammer look like some kind of native american totem, but such is the price.
And yes, the Spathovaklion makes all other blunt 1-handers obsolete (except maybe warhammer), and San's suggestion is right on; reduce the weight to like 1.4 kg, and it would have a decent niche as a faster blunt weapon with lower knockdown chance. Right now, it totally outclasses the Winged Mace, which was perfectly balanced with the other blunt 1h before the Spathovaklion was added.
1h internal balance needs a little work; every weapon above the "Sword" should have a niche (i.e. not be totally outclassed by another weapon in every stat). This is mostly true right now, with a few exceptions:
-Arming Sword is totally outclassed by Italian and Side Sword (I suggest +1cut or +2cut/-2pierce)
-Arabian Arming Sword is garbage (I suggest +1 speed at the very least)
-Long Arming Sword is totally outclassed by Knightly Arming Sword (I suggest +1 speed)
-Side Sword is too good (I suggest -1 cut)
-Spathovaklion should have its weight reduced to <1.5kg and probably lose 1 speed (so it's not faster than the picks)
-Give every 1h sword +3 cut +2 pierce at Masterwork (some unfairly get +3c/+3p right now)
