(Pov Kakashi)
"This blade is a piece of history, an heirloom unlike any most of you have seen before, a weapon that is of the Highest quality you can have before reaching the level of the Seven Swords of the mist or the Raijin of the Nidaime Hokage."
I let the words sink in as I show them the reforged blade.
"And yet it broke into pieces against a mere Kunai reinforced with "Earth Style Tetsu Kawa." Due to my mishandling of the blade even it couldn't stand up to such a simple Jutsu, this is why care of your main weapons is such an important thing everybody, whether you weapon is your body." Calmly point to Guy.
"Or if you use a Blade of a more imposing stature." I point to Hayate, the one true heir to the falling moon style.
"Now, for those of you who have a weapon you use as a main, singular weapon, this is the seminar for you, you should pay close attention because after the seminar I'm going to give out goodies to those who properly answer my questions."
With that I reach into my side pouch.
"THIS is Changzhi oil, it's a mix of Mineral and Clove oil, but it's no normal kind of Changzhi. No, it's from the land of iron, a very special kind of the Highest quality. Now many of you can't afford this but I have good news for you!" I say excitedly, for once I can do something I like, something that doesn't involve assassination.
"You see I found out some of their recipes which have allowed me to make a cheap yet decent quality replacement and I'll give you all some after the seminar."
The audience cheers half of the jonin in the stands shout my name, I wave my hand and then sit back down and shut up.
"Now I will also tell you that I've found a way to improve the oil in a way that nobody possibly could have thought of, I obviously can't tell you what I did but I am offering to do so for all of you tough it may take a few days to get everything I need, I will be giving a bottle of the improved Changzhi out after." Once again cheers fill the arena stands.
"Now, to properly clean a blade I will demonstrate for the academy students in the audience and some of the genin who aren't well versed in it yet." I Draw the White Light Chakra Saber from its sheath and grab a wet cloth. With it I wipe the blade gently. I then dry it with a second cloth before I grab the Uchiko powder and use it to remove the oil from the blade.
Then I wipe it clean once more with a dry cloth and apply the improved Changzhi to the blade before using a Jutsu to get rid of the excess, with that, I put it back in the sheath.
"That is how to clean, De-Oil and also Re-Oil a blade"
The audience claps but I look up and see some discontent.
"Now that's not all I'm showing you don't worry I just had to give a refresher and such, I'm not just showing you how to clean and what oil to use."
The audience watches with bated breath.
I redraw the blade and give it a small swish and the very air tears around it as I grab it with one hand I make half seals with the other. Tiger, Boar, Hare, and Ram, suddenly a steady stream of brown Chakra flows through the blade.
"This is one of the Techniques I made myself after feeling that actually having earth coating the blade was too much of a hindrance. That's when I came up with the idea to use the earth natured Chakra to coat the blade instead of actually reinforcing it with physical Earth. It uses the basic "Doryūheki" signs but stops after the fourth, then you flow the Chakra to the blade and let it condense slightly while not letting it actually produce earth. It's called "Ishi Moya"."
Suddenly I walk over to the foot thick steel plate and just stab through it with a grunt of exertion before slamming the side of the blade against it. The metal plate actually bends.
"Understand this is a difficult technique, any Uchiha in the audience I shall perform the technique for you again, please activate your sharingan, hyuuga you may use your byakugan if you wish." With that I go through the signs slowly letting each sign flow into each other letting what happens be clearer. Tiger, Boar, Hare, and Ram the blade once again is covered in the brown hazey Chakra. One of the uchiha gasps in shock before rushing out of the stadium in a panic towards the uchiha compound.
"Ahhhh, it always is lovely scaring the Uchiha." I lazily drawl while scratching the back of my hand, one of the hyuuga seems to have fainted. I suppose this is a technique that does break many pre-established notions on earth Chakra.
Some of the jonin pull out kunai and test it, many of them simply get a bit of dust to fall off their blades.
"No, no, no, you have to halt the completion of the technique to stop earth from forming." Suddenly a cheer goes up in the crowd as one of the jonin with a medic armband tossed a kunai covered in brown at the steel plate with about the force of a genin. I uncover my sharingan as the knife flies by, the brown is flickering and some small dust particles are falling off but it successfully punches through the steel with only a small scratch. I grab the knife out of the ground and "Shushin" to the stands.
"Good on you kid, what's your name." The girl who can't be older than 17 says
"It's Nohara Hanako, Hatake-san?" I drop the knife on the bleachers with a clatter.
As I scramble for my wallet. "Here." I pull out one of my many copies of my old team photograph and hand it to her. Her eyes widened.
"You had Nohara on your team?" I nod shakily before going back down to the podium.
"N-now let's start the questioning."
I try to compose myself while a few of the jonin look at me with pity.
"What technique broke the Hatake Heirloom?" Hayate yells out before I even get past broke.
""Earth Style Tetsu Kawa." I sigh as I toss him the bottle of improved Changzhi.
"Have a good day everyone." With that I walk out of the stadium. And make it home before I colapse in tears. This was a almost decent day, now all I have to do is have a little "talk" with Sandaime-Sama.
