Size variation

Race base weapon/tool size <- 10 [kg] Size tolerance <- (50% * str/1000), or say, 20%

If the size is bigger than tolerable, weapon speed severely slows down, tools become unusable if use time >* 0.75 second, the weapon/tool cannot be equipped. Small weapons/tools gains no (dis)advantage

When drawing: scale by (craftedWeaponSize / baseWeaponSize)

Crafted tool/weapon size is dependent to the baseRaceMass.
