I went 27/12 and it was very, very good.
Could spam almost everyone, did surprisingly high damage, I often killed people outright when I knocked them down, hit them, kicked them then hit them again; knockdown also has a pretty damn good chance (when you have a free hit, stab; does more damage. I didn't realise this for quite some time haha). Destroys armoured targets, aim for weak-spots (generally they have low body armour, face is always a good option though)
Very nice length on all swings, especially right.
Very cheap, 1 slot.
Also I found I glanced very, very little to not at all unless I completely screwed the swing up.
