i agree on your described use of the quarter staff in training, in real life.. allright there's less difference than in the other categories, but it's still considerable.

and i like the general idea, but that would be something for a Mount & Blade 2. a more flexible/organic system, where you have a ton of "skill levels", which wouldn't be visible on the character sheet in numbers of course.
example for a pickaxe1) a general combat level
2) a general melee skill level
3) a skill level for one-handed weapons
4) a skill level for one-handed axes
5) a skill level for the specific pickaxe
so if you are using a one-handed arming sword, skill levels 1), 2) and 3) will be useful, while skill levels 4) and 5) won't. and both arming sword and pickaxe will improve the common skill levels 1) - 3), but also different skills on a more specific level.
i just prefer organic character development to number-juggling.
