No.1 You got the charge attack wrong, silly. It is a downward slash towards the floor.

No.2 The sword should and won't be considered patented or otherwise copyrighted. The design seems to simple such that it makes no difference if you use it in Spiral knights.

No.3 You didn't balance it. What is the damage type? Damage? How are you gonna integrate it? Is it any different from the voltedge (because I don't think so). Basically it's just gonna be like a leviathan blade scissors?
