I would use this for more of deceiving the opponent, if I was to charge them with the staff/Lance without the pointed end, they would think they can slice through it, in reality I would have the upper hand and surprise them, hell even overpower them. The best part of this jutsu is how it is strong against lightning, we have seen how much people like to use nagashi for their swords. This CJ would help negate that, also it stays active for 3 turns meaning I don't need to constantly stream chakra. The worse part is, if the user has a dojutsu then the element of surprise is lost, and lets be honest, most deaths in the RP is because of snicky attacks.
I charge at the clone, with both my hands holding onto my Lancer (the blunt end facing the clone), I swing it with both my hands down in a vertical swing hitting the clone in the top of the head, right after I daze the clone, I then channel the fuuton chakra towards the blunt end sharpening it and then stab the clone in the stomach straight forward aiming for the stomach killing him.
