So instead of making my own 1h thread I'll use this one (and others).
For a one handed sword should I go;
Italian Sword: Slowest/Longest length/Highest cut
or
Espada Eslavona: Fastest/Shortest Length/Highest pierce
or
Side Sword: Balance of Both
If you have the gold to buy those and be ready to repair them more often, you should test them. They are neither bad by dmg, speed nor length. However I won't buy any of those (not only they do not fit my armor style, but they are also too expensive for me), but go with the Broad Short Sword and sometimes with the Long Arming Sword. Both have a nice damage for their price (26p/27c with 6,336 and 24p/30c with 6,708), plus their speed and length are nice too.
It also depends on you, what you prefer in combat. Some people like a shorter sword because they go very close to their enemy anyway. As long as you have your shield that also shouldnt be a problem. Once you lose it, a 2handed sword guy or polearm/piker could outrange you, probably even outspam by that range. There you have a disatvantage with a short range for sure. However this is always up to your personal opinion, which sword you like most in the end.
I played with a side sword with my old character some time ago and liked it, it felt nice, speed and damage wise.
I currently go and play a 15/21 build with 1hand/shield with shield skill 6, ath and wm 7 and less in IF and PS. However I just try to play with this in this gen and might take another build in the next gen, but I really like being fast currently. However I usually go by 5 ath and more IF/PS.
