『One-Handed Sword 』
Slash / Thrust
Diagonal / Slant
Non-System Assist Bonus
All players start with this skill, which involves equipping a sword light enough to be able to be lifted using one hand to either the left or the right hand. By using skills, related to it, you can level up this skill by around 1 point randomly, with a 10% chance, after 10 hits battling NPCs whose level has a discrepancy of no lower than 15 levels.
Since all players start with this skill, many (if not all) basic weapon skills come from this parent skill, and this is the skill with the most number of recorded weapon skills.

It was quite easy getting information about these data, mostly because 30% of the entire SAO population, including people I personally know, have mastered this «skill». However, I have my doubts over if I should include «Dual Blades» and «Holy Sword», mostly because I have no idea how to get those skills. («Kirito» even told me that he doesn't know.) However, I suspect it had something to do with mastering «One-Handed Sword». As for «Heathcliff»… let's just say it's been hard contacting that guy. He's too… calm, so I could presume that his «Unique Skill» requires both the mastery of «One-Handed Sword» and «One-Handed Shield».
"Stop bugging me…! *looking around for other information brokers* Even I don't know how it got to my «Skills List». It was … just there."
(Response: I always wonder why that guy dislikes that unique skill. I'd pay a fortune just to even know how that skill works!)
"«One-Handed Sword» is a practical skill, but I personally think it's a useless one, compared to «Two-Handed Sword». Even the «Rapier» sounds better. HAHAHAHAHA!
-A guy living in the «45th floor».
(Response: Understandable, because most «One-Handed Sword» users use a «Shield» of some sort. However, that guy should see some of the good solo players use that so-called "useless skill".)
