1) Not claiming that they can. the point is that the can wield them without penalty (a small shortsword is a Tiny Piercing weapon. How is this different from a stilletto?)
Combat training IS a martial art. Monks just study a different system.
Said tools use the same mechanics as a weapon. Heck, most weapons started as tools. And the point remains the same: A human has no problem manipulating tools and weapons whose weight and grip vary within a large margin. And, while these tools are designed for a specific function, so are the weapons that are modeled after them.
Given the wide range of weapons used by humans, and their comparitevly similar effects, what is a properly sized weapon?
As for the 'wife/hubby' example, the point was that humans can use smaller, misweighted items very effectively, with no further negative beyond skill. How much harder can it be for a fighter to use the same weapon?
2) I typed that a 3 year old can grip a shortsword ( and anything else 1" across). I also typed that a stronger halfling could manipulate said shortsword with the same grip.
3) How do you know that the system isn't on its way to said complexity in the first place (this being the basis of my obsession in the first place). There's already talk of a 4.0! Whether its true or simply a rumor, it gives cause for alarm. What else needs changing? You can say "just house rule it", but how often am I going to have to adjust my campaign/buy new core rules?
If I understood the rules, the weapons descriptions were abstractions for describing a number of weapons that fall roughly within the same perameters. It may not be called a longsword, but it fulfills the same function given the wide variances available. you not going to be able to accurately depict combat (its a slippery slope)
