- I'm Matt.

俺はケリー

- I'm Kerry.

ボルチモア・ナイフ＆ソードの

- [Matt] We are the Stagmer brothers

スタグマー兄弟だ

of Baltimore Knife and Sword.

俺たちは武器を作る みんなの お気に入りの武器

We're going to be building some of your favorite weapons

でも 誰も見たことのない武器を

and some weapons you've never seen before.

『マン・アット・アームズ リフォージド』

- [Kerry] This is Man at Arms. Reforged.

以前のビデオで話したが

- So if you've been watching

『リーグ・オブ・レジェンド』で

our League of Legends builds before

俺が主にプレイするのは

and we've talked about playing,

ランダムミッドだ

you'll know that I mostly play ARAMs.

ランダムミッドで

When you're playing ARAMs,

敵チームに いて欲しくない チャンピオンは

that one champ you don't want to see on the other team,

なんといっても

especially from a competent player,

マスター・イーだな

is Master Yi.

剣の材料は

To create Master Yi's blade,

4140ストック 3.5インチ径

I'll be using 3.5 inches of 4140 stock.

ネイゼル パワーハンマーで

I'll be knocking this down,

こいつを叩いて 板状にする

getting it down to a bar form using the Nazel power hammer.

この作業に 30分

It'll take me about a half an hour to get it down to a bar

それから 次に進める

and then we'll work from there.

[マット] ケリーの役目は 丸いストックを

- [Matt] Now that Kerry's done a lot of the brute forging

長い板状に

and really broken down this round stock

叩きのめすこと

into a nice long bar,

ここから イリアが

Ilya's going to take over from here

刃の部分を鍛造する

and start forging the blade.

叩いて 打ち伸ばしていく

He's going to continue drawing it out.

刀身の面と

He's going to work on both the flat

縁の両方に

and on the sides to make sure

交互に手を加え きれいに 打ち伸ばす

everything stays nice true as he draws it out.

イリアが刃に 水を吹きかけると

Here, you can clearly see where Ilya's spraying water

表面から薄片が

onto the blade as he's working

剥がれ落ちていく

and the scales popping from the surface.

薄片を除去するのは

The reason we want that scale to pop off

表面にくぼみが できないようにするため

is it can leave really deep pits in the metal.

今回 使える材料は

We have a really limited amount

限られている

of material to work from this time.

巨大な剣を作るため

We've got to make a pretty large blade

無駄は一切出せない

so we can't afford any loss.

左右対称だった先端が 鍛えられて

(thrilling music)

ゲームに出てくる剣と同じ

You can see now, Ilya's turning that symmetrical point

カタナの切っ先の形に 変わっていく

that he forged in into the more Tanto,

以前 キル・ビルの刀を

katana-like point that we're used to seeing in the game art.

作った時と 似た作業だ

You've seen Ilya do very similar work

イリアは早くも この国における

on the Kill Bill katana episode.

巨大な刀剣造りの 名人になりつつある

Ilya's quickly become one of the major masters

この手の仕事を受ける 職人は少ない

in this country at forging super large blades.

とんでもなく 巨大な剣を

Not too many people even take those commissions.

作って欲しいという

Many customers come, asking all different sword makers

注文は多い

if they'll make super huge large blades

この国で または世界でも

like you guys request.

巨大な剣を 一番多く 作ったのは イリアかも

Ilya has now forged more than

早くも 名工になった彼の

probably any of them in this country, maybe worldwide.

仕事を見るのは楽しい

He's quickly become a master

ここでイリアは 中子を作るため

and it's fun to watch him work.

柄の部分を外す

At this point, Ilya's removing the handle section

刃の部分が 長く延ばされたので

so that he can define the tang.

もう柄は必要ない

Doesn't need that handle on there for leverage anymore

ひっくり返す

now that the blade's drawn out so long.

パワーハンマーの下の 切断ツールを使う

He's flipped it over.

この部分を鍛えるため

He's using a hot cut tool underneath the power hammer.

切り離す

He's just going to remove that material,

パワーハンマーの出番は これで終わり

allow him to forge that section.

金床に移動して

Now that the power hammer work is done on this blade,

エッジを付け始める

Ilya's going to move to the anvil

きわめて鋭角なエッジを 付けるための作業を

and start forging in the bevels.

金床の端で行っている

You can see, as he works to get these really steep bevels,

特定の角度で 刃を支えて

he's working on the very edge of the anvil.

その角度に合わせて打てば

This is so that when he holds that blade at an angle

金床を叩かずにすみ

and strikes it matching that angle,

音が出たり 欠けさせたりしない

he doesn't hit the face of the anvil,

エッジを付ける作業に

dinging it or possibly chipping the anvil.

費やした時間は ここまで約１時間

To give you guys a sense of time,

切っ先の刃と マチの刃が

Ilya's been hand-beveling now for about an hour.

もうすぐ一つに

He's now at the point where he's joining

残りはあと ６インチ

the tip bevel into the shoulder bevel.

こんなに長い剣では

He's got about a six-inch section to go.

この手順は長くかかる エッジを付けるため

This is a long process,

熱すること20回

takes about 20 heats to get the bevel forged in

これが仕上がったら

on a big blade like this,

次は俺が研磨する番だ

so he's just going to stay at it

鍛造が終わり

and then I'll be ready to do the grinding.

研磨に取り掛かる

Now that the forging is done,

始める前に やるべきことがある

it's time to start the grinding.

この剣は 中国の九環刀

I have a few things I gotta work out before I start.

つまり９つの輪が （これの輪は２つだが）

This is a hybrid between a Chinese ring sword,

背についた刀と

which has nine rings down the back of the blade.

日本刀のハイブリッドだ

this only has two,

九環刀は 演武で使われるもので

and a Japanese katana.

非常に薄くて軽い

The Chinese ring swords are very flimsy and very light,

日本刀はとても分厚く 刃が張り出している

used in traditional forms.

二つの特徴を合わせる必要がある

Japanese katana's very thick and has very prominent edges

最初は 軽く磨いて

so I have to do a blend of them both.

それから刃に取り掛かる

I'm going to start by profiling just slightly

今日は

and then start on those heavy bevels.

『リーグ・オブ・レジェンド』の

(thrilling music)

環刀に付ける

- Today, I've been working

リングを作る

on the League of Legends ring sword

材質はブロンズ

and I'm doing the rings

そしてデザインは

that are going to hang from the sword.

自分の尾を食う ヘビに決めた

We're going to do them out of bronze

今はちょうど ウロコを彫っている

and we decided to do them

ウロコが仕上がったら

as the stylized snake that's eating its tail.

ブロンズで鋳造する 仕上げは明日

Now I'm in the process of carving the scales on it

ウロコが欠けていたら

and once the scales are carved on it,

彫金ツールで刻み直す

we'll cast it in bronze and then finish it tomorrow

[ケリー] 鋳造は ロストワックス法で行う

and any place where I've lost the scales,

ロウのパーツをつなげ 原型を作る

I'll be able to put them back on with the chasing tool.

原型をフラスコに入れ

- [Kerry] We'll be doing these castings with lost wax.

インベストメントという特殊な

First we take the waxes and screw them into a tree.

石膏を流し込む

Then they're set into a flask

窯に入れる

and plaster is poured around them.

ゆっくり1350度に加熱し

It's a special plaster called investment.

1000度に下げる

It'll go into the kiln.

鋳造機にセットし

We slowly ramp up to 1350,

それから2100度の

lowered to a thousand.

熔けたブロンズを注ぎ

It'll be placed into the casting machine

真空鋳造機に入れる

and then I'm going to bring in

900度になったら

molten, 2100-degree bronze

水に入れる

and pour it into the vacuum machine.

石膏が剥がれ

After it reaches 900 degrees,

ブロンズが現れる

we'll take it to the water,

焼入れ前の 最後の手順

it'll steam off the investment,

リングをつける 場所を決めて

and show us our bronze.

ドリルで穴を開ける

- The last step before heat-treating the blade

刃の焼入れの 準備ができたので

is to get those holes located and drilled in

鍔(つば)に取り掛かる

where our rings will go after.

これまでの 『リーグ・オブ・レジェンド』の

Now that we got our blade ready for heat treating,

剣造りと同様 多くの場合 スプラッシュアートと

its time to move onto the guard portion.

ゲーム内アートには違いがある

Just like in some previous League of Legends builds,

鍔の位置を定める必要がある

the splash art doesn't always match with the end game art

マスター・イーの基本スキンの

so I've had to do a little figuring out,

スプラッシュアート

see where I want to go with this guard.

このデザインをベースに ここまで来た

This is the main splash art for Master Yi

だが集めた資料は どれも鍔と刃が

for his basic standard skin

正面から描かれていない

and this is what we've based our design off so far.

そこでこの部分に ズームインして

Unfortunately, all the pictures I can find of it

しっかり見て

have that guard and the blade off angle

鍔の形を想像し

so what I had to do was kind of zoom in here,

絵を描き起こす

take a good look at everything,

その次に

and I just freehand drew

ここにある中心点から 対称にする

what I thought the guard would look like.

もう少し線を描き込む

What I'm going to do now is I'm going

刃が取り付けられるのはここ

to mirror it over from the center point here.

真ん中には

Just gotta fill in a few lines.

宝石か何かをはめ込み

The blade will come out of this section.

境界線を際立たせるため 浮き彫りをする

Probably going to set a stone

こんなところだろう

or something like that in the middle,

鍔の部分は ６つのパーツで作る

cut some overlays to make those borders rise out.

中央のウィング部

We'll be good to go.

鍔ブロック

(thrilling music)

外側のピース

So we have six different pieces that make up this guard.

ナイスな縁飾りに なる予定

We have our central wings,

鍔ブロックのピースは

we have the quillon block,

まっすぐに平らに 取り付けるのではなく

and then the outer pieces

ブレード寄りの

which are going to make it look like a nice rise border.

角度をつけるため

What I have to do now

柄の側は厚く

is I gotta take both of these quillon block pieces

刃の側は薄くする

and instead of them being nice and flat,

マスター・イーの大刀の焼入れ

we want them to angle towards the blade

この刃の素材は4140スチール

so they're thicker at the handle

ジャックハンマービットや ハンマーダイス その他の

and thinner at the blade.

インパクト工具に 最適な鋼材だ

(suspenseful music)

炭素含有量は約0.4%

- (mumbles) heat treat Master Yi's sword, his Da-dao.

より含有量の多い 他の素材と違い

This blade is made out of 4140 steel.

あまり温度に 注意する必要がない

It's an excellent steel for jackhammer bits,

だが マンガンと クロムを多く含む

hammer dies and other impact tools.

言い換えると この刃には

4140 has approximately 0.4% carbon,

刃紋が出ない

means I don't have to watch my temperatures

この鋼が深焼きのためだ

as carefully as some other higher carbon steels

水に浸して芯まで冷却する

but it has tons of manganese and tons of chrome in it.

[ケリー] イリアが 長い炉に

This means if I were to try to hamon this blade,

刃を入れ 鉄が非磁性になる

it would not show any hamon

高温まで熱し

because it's a deep-hardening steel

取り出して 冷却する

and the quench goes all the way under the clay to the spine.

マスター・イーの大剣は

- [Kerry] Ilya now goes into our long furnace

これで最高の硬度となった

brings this piece up to critical temperature

ただ素材が4140スチールなので

to where it's non-magnetic,

高炭素鋼ほどには 硬くはならない

brings it out, and takes it to the quench.

音を聞いてみな

- So I quenched Master Yi's Dadao.

ガラスみたいな音には ならない

It is at full hardness now.

油焼入れで この刃の硬度は

However, because it's 4140,

最高で

it doesn't get hard as the high-carbon steels.

ロックウェル硬さ55、51

Check this sound out.

もし素材が 1075か1095なら

It doesn't have that glassy sound because it's 4140.

油焼入れで ロックウェル硬さ60～61

Its highest hardness I can get on this blade

マスター・イーの剣をタンクに入れ

in oil quench is about

約１時間経過

let's say 55, 51 Rockwell.

焼入れ工程で 冷却時のゆがみを

The highest hardness it can get out of 1075, 1095

直せるのは これが 最後のチャンスだ

can be up to 60-61 Rockwell in an oil quench.

取り出して

Master Yi's sword has been in the tank

万力を使い ゆがみを直す

for about an hour already.

マスター・イーの剣は これで基本 まっすぐ

In the tempering, this is actually the last opportunity

他のゆがみは 刃入れの時に

to straighten out any warps produced in the quenching.

研磨して直す

So, I'm going to take it out

マスター・イーの武術大剣の

and go to the vise to quickly yank some of them straight.

熱処理と焼入れは完了

So Master Yi's sword is basically straight.

これで 研磨に進める

Any other warping along the edge will be fixed in the grind

まずは80グリットで

when it's being made sharp.

ディープスケールを

- Now that we have Master Yi's Wushu blade

全て除去し それから グリットを 上げてゆく

completely heat-treated and tempered,

120グリットと 220グリットでの

I can move onto the polishing.

ブレードの研磨が これで完了

My first goal is to start at the 80 grit

ナイロンたわしで仕上げる前に

and remove all the deep scale

やるべきことはあるが

and then I'll go through the grits from there.

刃と峰が一つとなる 切っ先の仕上げは完了

(uptempo music)

棟に少々 面取りを施した

All right, so I just ran this blade through the grits,

より攻撃的に 見えると思う

120, 220, I got a little more polishing to do

ここまでの出来は上々

before I move onto the Scotch-Brite

次は 握りと 柄頭に取り掛かる

but I was able to define that kissaki,

剣の柄頭は

which is where the two different bevels come together.

黒い鉄パイプと

I add a small back bevel on the spine.

２本の丸棒という 合計３つの部品で作る

Just think it looks a little more aggressive and I like it.

２つの矢じり型装飾に 鍛造する

Really happy with it so far.

先端装飾の鍛造では

Time to get that hilt and the pommel on.

最初の形がとても重要

- The pommel for Master Yi's sword

丸棒から切り出した この材料を

will be constructed from three pieces

平たく加工し

of black iron pipe and a couple pieces of round bar.

２つのマチを形作り

It'll be forged into two arrowhead finials.

それから 金床の縁を使って

When forging finials like this,

この形を

the pre-form is very important.

こういう形にする

So I'm going to take a piece of this round bar

それから 面取りをして

and I'm going to flatten it out,

この先端を延ばす

and then I'm going to form two shoulders

それから磨き上げて こんな風にする

and then using the edge of the anvil,

１、２、３

I'm going to buck that shape

剣の柄頭として

to get a shape like this.

サムが２つの尖端を 鍛造した

And then from there, I'll bevel them

左と右に使う

and draw that point more

基本的には上部から スパイクを突き出させ

and then it'll get cleaned up to look like that.

そしてフィットするよう

So one, two, three.

小面を刻む予定

- So for the pommel on Master Yi,

柄頭の主体となる

Sam's already forged out a couple of the points

パイプの部分に かっちりとはまるはず

that go to the left and right.

これらはしっかりと溶接され

I'm going to be basically turning a spike out the top

剣全体をひとつにつなぐ

and then we'll probably do

[マット] 柄頭を作るにあたって

some faceting on it to get the fit.

パイプのピースを２つ使用する

It'll lock down into a pipe section

片方にはノッチを作り もう一方は先端をＶ型にする

that'll become the main part of the pommel.

２つは組み合わされて しっかりと溶接される

All that's going to get welded solid
