I'd think swords, at the very least one-handed swords, would be the least dependent on STR out of the three main melee weapon types. So far, the only sword I've seen that isn't majority-STR, has been the Hakouhen Masterwork Katana, with 30% STR / 70% SKI. When I think of a sword, I think of something you're wielding with finesse -- something where you're utilizing complex, skillful maneuvers to get in through openings in an opponent's guard.

Contrast axes, which are all about crushing a wedge through said guard and hacking apart shields and armor, and spears, which are just as much about hard, piercing thrusts and utilizing the leverage of a long weapon.

Personally, I feel like it would better reflect the theme of one-handed swordsmanship styles to have minimal STR scaling, in favour of SKI instead. The lightest among the swords (tarnada, hakouhen, etc.) should likely have no STR scaling. I would suggest replacing it with CEL instead -- these types of swords are meant to be used by light-footed, quick sorts of characters. They are sharpened to a keen edge and wielded with finesse.

~Heavy~ swords, on the other hand (read: the ones that end up being affected by the upcoming Two-Handed talent), should be all about STR scaling, and maybe some VIT. Large swords like the claymore, and even the bastard sword, were sharpened much less keenly than smaller swords. A portion of the claymore's blade is even left ~unsharpened~, and there's a second handguard above it, because at times you need the extra leverage to manage its length and weight. These swords function more like axes, in that they rely much more on their weight and the force behind the blow in order to crush past opponents' guard. These swords were used with wide, sweeping arcs to discourage the approach of lighter-armored foes.
